>                 URL: https://issues.apache.org/jira/browse/GROOVY-8507
>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler
>    Affects Versions: 2.4.5
>         Environment: Linux ubuntu-xenial 4.4.0-116-generic #140-Ubuntu SMP Mon Feb 12 21:23:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
>            Reporter: Álvaro Iradier
>            Assignee: Eric Milles
>            Priority: Major
>             Fix For: 3.0.0-beta-3

>          Time Spent: 0.5h
>  Remaining Estimate: 0h

> This problem was discovered in a Jenkins pipeline, but then nailed down and found it failed with *groovyc* compiler too.
> Creating a script with two nested enums, like:
> {code:java}
> class TestClass {
>     enum OuterEnum {
>         VALUE,
>         enum InnerEnum {
>             A
>         }
>     }
> }
> {code}
> And compiling with groovyc script.groovy makes the compiler freeze with 100% CPU usage.
> In Jenkins, this results in the Job and executor being freezed and zombie (need to kill the job and executor thread), but I am reporting this to Jenkins as an independent issue.
> As the problem seems to happen in a stripped down groovy script, I am reporting it here too.
