0.8.2
New Features
- Experimental support for Java 11 and Java 12 class files, including JEP 12 "preview features" (GitHub #719, #738, #743).
- Branches and instructions generated by javac 11 for try-with-resources statement are filtered out (GitHub #669).
- Synthetic classes are filtered out during generation of report (GitHub #668).
- Part of bytecode generated by ECJ for
switch
statements onjava.lang.String
values is filtered out during generation of report (GitHub #735, #741, #746). - Methods added by the Kotlin compiler that do not have line numbers are filtered out during generation of report. Idea and implementation by Nikolay Krasko (GitHub #689).
- Branch added by the Kotlin compiler for reading from
lateinit
property is filtered out during generation of report. Implementation by Fabian Mastenbroek (GitHub #707). - Bytecode generated by Kotlin compiler for implicit
else
ofwhen
expressions that list all cases ofenum
orsealed class
is filtered out during generation of report (GitHub #721, #729, #749). - Additional bytecode generated by Kotlin compiler for when expressions on
kotlin.String
values is filtered out during generation of report (GitHub #737, #746). - Classes and methods annotated with annotation whose retention policy is
runtime
orclass
and whose simple name isGenerated
are filtered out during generation of report (GitHub #731). - Maven goal report-aggregate now also considers dependencies specified using version range. Idea and implementation by Lukas Krejc (GitHub #658).
Fixed Bugs
- Don't insert stackmap frames into class files with version < 1.6, this fixes regression which was introduced in version 0.6.5 (GitHub #667).
- Question mark in filter expressions now correctly matches exactly one character (GitHub #672).
- Part of bytecode that javac generates for
switch
statement onjava.lang.String
values with a small number cases is now correctly filtered out during generation of report (GitHub #730).
Non-functional Changes
- JaCoCo now depends on ASM 6.2.1 (GitHub #706, #725).
- Improved error message when already instrumented classes are used for instrumentation or analysis (GitHub #703).
- JaCoCo build now requires at least Maven 3.3.9 and JDK 8 (GitHub #711).
API Changes - The XML report now has an optional attribute
sourcefilename
on theclass
element to allow unambiguously relate classes to source files. The JaCoCo DTD version has been updated to 1.1 (GitHub #702).
0.8.1
0.8.0
New Features
- JaCoCo now officially supports Java 9 (GitHub #600).
- JaCoCo now comes with a simple command line interface (GitHub #525).
- Limit configuration of Maven
check
goal and Antcheck
element now also supports percentage values (GitHub #534). - Manifests of JAR files now have
Automatic-Module-Name
for Java 9 (GitHub #565). - Maven aggregated reports will now also include modules of
runtime
andprovided
dependencies (GitHub #498, #572).
During creation of reports various compiler generated artifacts are filtered out, which otherwise require unnecessary and sometimes impossible tricks to not have partial or missed coverage:
- Methods
valueOf
andvalues
of enum types (GitHub #491). - Private empty no-argument constructors (GitHub #529).
- Methods annotated with
@lombok.Generated
to better integrate with Lombok >= 1.16.14. Initial analysis and contribution by Rüdiger zu Dohna (@t1) (GitHub #513). - Methods annotated with
@groovy.transform.Generated
to better integrate with Groovy >= 2.5.0. Thanks to Andres Almiray (@aalmiray) for adding the annotation to Groovy (GitHub #610). - Part of bytecode for
synchronized
blocks (GitHub #501). - Part of bytecode for try-with-resources statements (GitHub #500).
- Part of bytecode for
finally
blocks (GitHub #604). - Part of bytecode for
switch
statements onjava.lang.String
values (GitHub #596).
Note: Tools that directly read exec files and embed JaCoCo for this (such as SonarQube or Jenkins) will provide filtering functionality only after they updated to this version of JaCoCo.
Fixed Bugs
- Fixed bug in instrumentation of exception handlers, which was causing damage of structured locking in certain situations and as consequence poor performance of instrumented methods, analysis and fix contributed by Allen Hair (@allenhair) (GitHub #627).
dump
commands now report error when server unexpectedly closes connection without sending response (GitHub #538).- Reduced chance of conflict with other agents (GitHub #555).
- Restored Maven
help
goal that was missing in version 0.7.9 (GitHub #559). NullPointerException
during offline instrumentation of module-info.class (GitHub #600, GitHub #634).- Incorrect update of frames caused by bug in ASM library (GitHub #600).
- Loss of
InnerClasses
attribute caused by bug in ASM library (GitHub #600). NegativeArraySizeException
during instrumentation caused by bug in ASM library (GitHub #600).
Non-functional Changes
0.7.9
Fixed Bugs
- "
java.lang.ClassFormatError: Short length on BootstrapMethods in class file
" caused by bug in ASM library (GitHub #462). - Do not recompute frames in case of large methods, otherwise
java.lang.ClassNotFoundException
might be thrown (GitHub #177). ExecutionDataWriter.FORMAT_VERSION
is not a compile-time constant (GitHub #474).- Maven goal "prepare-agent" should not overwrite existing property value if execution was skipped (GitHub #486).
API Changes
JaCoCo.ASM_API_VERSION
removed (GitHub #474).
Non-functional Changes
- JaCoCo now depends on ASM 5.2.
- OSGi metadata now generated automatically and additionally include
uses
directives,Require-Capability
attribute, and export of all internal packages withx-internal:=true directive
(GitHub #211). - Removed OSGi attributes that were mistakenly added in version 0.6.1 into
jacocoant.jar
that contains all dependencies (GitHub #211).
0.7.8
New Features
- User property
jacoco.dataFile
for parameterdataFile
of Mavenreport
goal (GitHub #322).
Fixed Bugs
- Use
RoundingMode#FLOOR
instead ofRoundingMode#HALF_EVEN
for percentages in HTML report, so that "99.5" is displayed as "99%", not as "100%" (GitHub #452). - Do not add useless members into Java 8 interfaces that have only interface initialization and abstract methods (GitHub #441).
- Fix instrumentation to not violate Java Virtual Machine Specification regarding initialization of final fields, otherwise
IllegalAccessError
will be thrown starting from OpenJDK 9 EA b127 (GitHub #434). - Fix instrumentation of interfaces with default methods to not create incorrect constant pool entries, which lead to
IncompatibleClassChangeError
starting from OpenJDK 9 EA b122 (GitHub #428). - Add Maven goal report-aggregate to lifecycle-mapping-metadata.xml (GitHub #427).
Non-functional Changes
0.7.7
New Features
- New Maven goal report-aggregate to create reports for multi-module projects (GitHub #388).

- Renamed "dot" resources in generated HTML reports to become more web hosting friendly (GitHub #401).
- Experimental support for Java 9 class files (GitHub #406).
Fixed Bugs
- Don't suppress EOF errors in case of truncated execution data files (GitHub #397).
Non-functional Changes
0.7.6

inclnolocationclasses
to support execution environments like Android where no source location is provided with classes (GitHub #288). - Improved error message in case of incompatible execution data files. (GitHub #319).
- Command line agent options now supports comma in file names. Contributed by Jochen Berger. (GitHub #358).
Fixed Bugs
- Fix
MBeanClient
example (GitHub #333). - Avoid
ConcurrentModificationException
during shutdown (GitHub #364).
API Changes
- In case of incompatible execution data formats read from another JaCoCo version
ExecutionDataReader.read()
now throws aIncompatibleExecDataVersionException
.
Non-functional Changes

New Features
- Better detection of coverage in code blocks with implicit exceptions. (GitHub #310).
- Added
lifecycle-mapping-metadata.xml
for M2E (GitHub #203). - Allow locales with country and variant for Ant report task (GitHub #289).

API Changes
- The exec file version has been updated and is not compatible with previous versions.
0.7.4
0.7.3

Fixed Bugs
- Instrumented bytecode now compatible with Android ART runtime, analysis and fix contributed by Allen Hair (GitHub #265).
