-------------------------------------------------------------
{{StackOverflowError}} resolved in Groovy 2.5.14+.
To get your example project to run test successfully, I needed to make a small
change:
{code:groovy}
class Library {
@groovy.transform.TypeChecked
GenericConsumer findOrCreateTheProblematicClass(String aCategory) {
GenericConsumer problemClass = anotherTestMethod { ->
Class<? extends GenericConsumer> gc =
GenericConsumer.findSpecificType(aCategory)
gc.testMethod()
}
return problemClass
}
{code}

> Key: GROOVY-9565
> URL: https://issues.apache.org/jira/browse/GROOVY-9565
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 2.5.11, 2.5.12, 2.5.13
> Reporter: Daniel Demus
> Assignee: Eric Milles
> Priority: Major
> Labels: StackOverflowError
> Fix For: 2.5.14
>
>
> If you try to compile the project at
> [https://github.com/demus-nine/groovy-class-generic-stackoverflowerror]
> groovyc crashes with a StackoverflowError. This happens in
> org.codehaus.groovy.transform.stc.StaticTypeCheckingSupport#applyGenericsContext(java.util.Map<org.codehaus.groovy.ast.GenericsType.GenericsTypeName,org.codehaus.groovy.ast.GenericsType>,
> org.codehaus.groovy.ast.ClassNode) in this bit of recursive code:
> {code:java}
> if (bound.isArray()) {
> return applyGenericsContext(spec, bound.getComponentType()).makeArray();
> }
> {code}
> although I have seen it throw in other methods in the
> StaticTypeCheckingSupport class.
>
> The class that is being handled is an abstract class with a generic
> parameter, but in the code using the type there aren't enough hints to the
> compiler to resolve the generic constraint, possibly because it is
> self-referential.
