>             Project: Groovy
>          Issue Type: Bug
>          Components: Compiler
>    Affects Versions: 2.4.16

> 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.
