Issue with CompileStatic and Gpars agent

[Paolo Di Tommaso]

Dear all, 

I'm cross-posting this issue because it's hard to understand if it'd Groovy or Gpars problem. 

When running the following piece of code, I'm getting exception below 

import groovyx.gpars.agent.Agent

import groovy.transform.CompileStatic

@CompileStatic

class Dummy {

  def void foo() {

     def x = new Agent<List>( [] )

     x.send { List it -> it.add(1) }

     x.await()

  }

}

new Dummy().foo()

java.lang.IllegalAccessError: tried to access class groovyx.gpars.agent.AgentBase from class Dummy

at Dummy.foo(ConsoleScript15:10)

at Dummy$foo.call(Unknown Source)

at ConsoleScript15.run(ConsoleScript15:16)

The guilty line is "x.await()". If I remove the @CompileStatic it works fine. 

Any clue? 

Cheers,

Paolo

“””

  def void foo() {

“””

Looks a bit strange to me.

Try with only ONE of ‘void' OR ‘def'?

Just an update on this. I believe the problem is that the class AgentBase is not declared public in GPars. 

I've opened the following issue:

I've made some other tests and it turns out that Java allows to access a public method inherited from a non-public class.

I'm starting to think that this is a @CompileStatic issue which resolve wrongly the method declaration. In fact the exception trace reports 

java.lang.IllegalAccessError: tried to access class groovyx.gpars.agent.AgentBase from class Dummy

at Dummy.foo(ConsoleScript15:10)

at Dummy$foo.call(Unknown Source)

at ConsoleScript15.run(ConsoleScript15:16)

While the method is inherited the Agent class so it should be accessible. 

Thoughts?

Cheers,

Paolo

Hi Bob, 

No, is not that. I think it is a @CompilerStatic related problem. 

I've opened an issue for it

https://jira.codehaus.org/browse/GROOVY-6962

Best,
Paolo
