Compilation error when using @CompileStatic with closures as constructor parameters

[sdudley]

groovy-sandbox 1.7 is causing a compilation error when I try to use it on a @CompileStatic'ed method which creates an object that accepts a closure as a constructor argument. I am testing against Groovy 2.3.4.

I mocked up a very simple example of what is going on here:

• The problem code - test3.groovy
• Setup for the sandbox - sandboxLoader.groovy

Making any of the following changes allows this to compile without errors:

1. remove the @CompileStatic from staticRunner() in test3.groovy,
2. call the no-args constructor rather than using the closure variant
3. set sandboxTransformer.setInterceptMethodCall(false) when setting up the CC, or
4. disable the sandbox entirely

In the cases where it does not work, the resulting exception is as follows:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
General error during class generation: size==0

java.lang.ArrayIndexOutOfBoundsException: size==0

I've noticed that a bunch of other things don't work properly with @CompileStatic either; I imagine that it may not be supported yet (although I think I saw in one of the other comment threads that Groovy 2.3 hasn't been officially tested either).

If you need more details, let me know and I can post the other test cases.

I would not expect @CompileStatic to ever work.
