Magnus Reftel commented on GROOVY-7826:
---------------------------------------
Tested with a couple of different versions, and it seems like the problem was
introduced in 2.2.0-beta-2, as all tested versions up to and including
2.2.0-beta-1 works.
Log follows:
$ for a in ~/opt/groovy-*; do echo `basename $a`; $a/bin/groovy -cp .
repro.groovy; done
groovy-1.8.9
groovy-2.1.9
groovy-2.2.0

> Infinite recursion in genericTypeAsString
> -----------------------------------------
>
> Key: GROOVY-7826
> URL: https://issues.apache.org/jira/browse/GROOVY-7826
> Project: Groovy
> Issue Type: Bug
> Affects Versions: 2.4.6
> Environment: Groovy Version: 2.4.6 JVM: 1.8.0_91 Vendor: Oracle
> Corporation OS: Linux
> Reporter: Magnus Reftel
> Labels: regresion
> Attachments: groovy-7826.zip

>
> The following two Java classes C1 and C2 cause Groovy to enter infinite
> recursion in genericTypeAsString when a method that takes a C1 is declared:
> C1.java:
> public class C1 <T2 extends C2<T2,T1>,T1 extends C1<T2,T1>> { }
> class C2<T2 extends C2<T2, T1>, T1 extends C1<T2, T1>> { }
> repro.groovy
> def f(C1 c1) { }
> This is reduced from actual code in Jenkins, where Run and Job have type
> parameters like this.
