[jira] [Created] (GROOVY-8944) groovyc: invalid constant pool entry

-----------------------------------

             Summary: groovyc: invalid constant pool entry
                 Key: GROOVY-8944
                 URL: https://issues.apache.org/jira/browse/GROOVY-8944
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 2.4.16
            Reporter: Eric Milles


Updated our projects to Groovy 2.4.16 today and ran into a problem with one of our test helpers.   This functional interface performs a similar function to {{GroovyAssert.shouldFail}}.  Whenever it is referenced from statically compiled Groovy, there is a bytecode error for the reference to {{java.lang.Throwable}}.  This error is not present in Groovy 2.4.15, which should help isolate the cause.

java.lang.VerifyError: Illegal type at constant pool entry 53 in class CatchableTest
Exception Details:
  Location:
    CatchableTest.testTryCatch()V @14: invokestatic
  Reason:
    Constant pool index 53 is invalid
  Bytecode:
