Parsing java has failures in hashing #1599

asfalcone · 2020-10-29T15:14:05Z

Describe the bug
Parsing java has failures in hashing

To Reproduce
https://cs.android.com/androidx/platform/tools/dokka-devsite-plugin/+/master:testData/fragment/source/ Using the source of the Android Jetpack Fragment library we often (but not always) see two kinds of errors in hashing from findVirtualFileForTopLevelClass

Getting the same issue.
Android project, Dokka 1.4.10.2
Just added in Dokka as a replacement to the Javadoc as I need to start adding Kotlin code.

Randomly getting:

During rehashing, Trove discovered that the following two objects claim to be equal (as in java.lang.Object.equals() or TObjectHashingStrategy.equals()) but their hashCodes (or those calculated by your TObjectHashingStrategy) are not equal.This violates the general contract of java.lang.Object.hashCode().

Any news on this? Getting it quite frequently

i will try do work on it or at least get some help from the compiler team

@harri35 could you post your project so i can have a little more data about the issue?

harri35 · 2020-12-10T13:04:49Z

@MarcinAman Sorry, the project source code is proprietary and I can't post it. If there are any files / logs from the build process then maybe I can provide these.
A few things from the project:
It is 95% Java, 5% Kotlin. Just started moving to Kotlin. That is why the need for Dokka also.
The project itself is a library that has a dependency library which it is wrapping and which has a lot of similar classes. As there is a rule that we can't provide the UI the classes directly from our internal library. Maybe the existence of the similar classes is an issue there.

I've experienced this a couple of times today since upgrading from 0.10 to v1. Here's the project: https://github.com/relaycorp/relaynet-cogrpc-jvm

The bug seems to appear randomly and it is hard to reproduce. Here is a run where it failed:
https://github.com/AlchemistSimulator/Alchemist/runs/1800103044?check_suite_focus=true

Here is the corresponding Gradle build scan: https://scans.gradle.com/s/6pyir6cwg3nts

Other runs on the same code base worked.
