-------------------------------------
> Trait compilation error: IllegalArgumentException: Comparison method violates its general contract!
> ---------------------------------------------------------------------------------------------------
>
> Key: GROOVY-7387
> URL: https://issues.apache.org/jira/browse/GROOVY-7387
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.3.6, 2.4.3
> Environment: Using 32-bit Oracle JDK 1.7.0_45, Groovy 2.4.3 with InvokeDynamic enabled (also reproducible using 2.3.6)
> Reporter: Andy Belsky
> Assignee: Cédric Champeau
> Priority: Critical
> Fix For: 2.4.5
>
> Attachments: sample-7387.tgz

> The smallest sample I could create is the following.
> We've got two Groovy classes, one of which is a trait and another implements that trait.
> {code:title=TestTrait.groovy}
> package test
> trait TestTrait {
> Object userRepository
> Object respondentRepository
> Object surveyStatsRepository
> Object surveyRepository
> Object questionRepository
> Object questionOptionRepository
> Object answerRepository
> Object surveyInvitationRepository
> Object invitationDeliveryRepository
> Object surveyPatternRepository
> Object accessNumberRepository
> Object deliverySubscriberRepository
> }
> {code}
> {code:title=TestClass.groovy}
> package test
> class TestClass implements TestTrait {
> }
> {code}
> Then let's compile those using the command line:
> {code}
> $ JAVA_HOME/bin/java -cp ../lib/groovy-all-2.4.3.jar org.codehaus.groovy.tools.FileSystemCompiler -cp ../lib/groovy-all-2.4.3.jar test/*
> {code}
> This results in the following compiler error:
> {code}
> org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
> General error during canonicalization: Comparison method violates its general contract!
> java.lang.IllegalArgumentException: Comparison method violates its general contract!
