Error Prone 2.2.0
New errors:
- [ComparableType] A new check for detecting incompatibility of types between the type of a class implementing
Comparable<T>andT. - [ConditionalExpressionNumericPromotion] A conditional expression with numeric second and third operands of differing types may give surprising results.
New warnings:
- [CatchFail] detects tests that ignore exceptions and then call
fail() - [ModifyCollectionInEnhancedForLoop] detects collections modified within loops.
- [ThreadLocalUsage] ThreadLocals should be stored in static fields.
New optional checks:
- [StringSplit] detects
String.split(String), which has surprising behaviour. - [StringSplitter] refactors uses of
String.splittoSplitter. - [TypeParameterNaming] enforces that type parameters are named according to the google style guide.
- [RandomCast] casting a random number in the range
[0.0, 1.0)to an integer or long always results in0.
Changes to existing checks
- ArrayEquals now detects misuse of
android.support.v4.util.ObjectsCompat#equals. - EqualsIncompatibleType now detects misuse of
android.support.v4.util.ObjectsCompat#equals. - SizeGreaterThanOrEqualsZero now detects misuse of common Android-specific collections.
- FilesLinesLeak was renamed to StreamResourceLeak, and now checks other methods in Files.
- FunctionalInterfaceClash is no longer enabled by default.
- JUnit4{SetUp,TearDown}NotRun will find methods that look like setup or teardown methods, but have a
@Beforeor@Afterannotation that are notorg.junit.Beforeororg.junit.After. - SimpleDateFormatConstant now handles all
DateFormats, and is renamed to DateFormatConstant - Disable RestrictToEnforcer by default (fixes #812).
- EqualsIncompatibleType/PredicateIncompatibleType/CollectionIncompatible now explore type parameters to ensure their compatibility:
Foo<A>is incompatible withFoo<B>ifAandBare incompatible with each-other.
