Eric Milles commented on GROOVY-11770:
--------------------------------------
In order to determine {{LowestUpperBound(Job,Pod)}} it is trying to fill in the
type args for {{Editable}} which requires {{LUB(JobBuilder,PodBuilder)}}. This
in turn is trying to fill in {{VisitableBuilder}} and requires {{LUB(Job,Pod)}}
to do so.
The loop prevention is not deep. It describes the case for {{Comparable}}:
{code:java}
ClassNode t1 = upperBound(agt[i]);
ClassNode t2 = upperBound(bgt[i]);
ClassNode basicType;
if (areEqualWithGenerics(t1, isPrimitiveType(a)?getWrapper(a):a) &&
areEqualWithGenerics(t2, isPrimitiveType(b)?getWrapper(b):b)) {
// "String implements Comparable<String>" and "StringBuffer
implements Comparable<StringBuffer>"
basicType = fallback; // do not loop
} else {
basicType = lowestUpperBound(t1, t2);
}
{code}

> When processing a file using the kubernetes-client library, the Groovy
> compiler recurses endlessly parsing the generics.
