Daniel Demus updated GROOVY-9565:
---------------------------------
Description:
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.
