CtConstructor.getAvailableParameterAnnotations() returns wrong number of arguments for inner class with annotations

[magicwerk]

The following snippet shows that CtConstructor.getAvailableParameterAnnotations() returns a wrong number of arguments for inner class with annotations.

Output:

Class OkWithoutParamAnnotation: paramCount=2, annotatedParamCount=2 CtClass ShowBugParameterAnnotationsInnerClass$OkWithoutParamAnnotation: paramCount=2, annotatedParamCount=2 Class ErrorWithParamAnnotation: paramCount=2, annotatedParamCount=2 CtClass ShowBugParameterAnnotationsInnerClass$ErrorWithParamAnnotation: paramCount=2, annotatedParamCount=1

Note the bold highlighted value 1 which should also be 2. This has been tested with org.javassist:javassist:3.28.0-GA.
