Paul King closed GROOVY-6651.
-----------------------------
> Calling a closure declared as a field from within another closure
> -----------------------------------------------------------------
>
> Key: GROOVY-6651
> URL: https://issues.apache.org/jira/browse/GROOVY-6651
> Project: Groovy
> Issue Type: Bug
> Components: groovy-runtime
> Affects Versions: 1.8.9, 2.1.9, 2.4.0-beta-3
> Reporter: Andreas Lang
> Priority: Minor
>
> The following test demonstrates the problem:
> {code}
> class MemoizedClosureTests {
> static class Pogo {
> def myMemoizedClosure = { String lalala -> }.memoize()
> void doSomething() {
> 1.times {
> myMemoizedClosure('hello')
> }
> }
> }
> @Test
> void testMemoizedFieldFromWithinClosure() {
> new Pogo().doSomething()
> }
> }
> {code}
> This causes the following exception:
> {code}
> groovy.lang.MissingMethodException: No signature of method:
> org.codehaus.groovy.runtime.memoize.Memoize$MemoizeFunction.doCall() is
> applicable for argument types: (java.lang.String) values: [hello]
> Possible solutions: call(), call([Ljava.lang.Object;),
> call(java.lang.Object), call([Ljava.lang.Object;), findAll(),
> equals(java.lang.Object)
> at
> cern.ais.plugin.MemoizedClosureTest$_Pogo_doSomething_closure2.doCall(MemoizedClosureTest.groovy:13)
> at
> cern.ais.plugin.MemoizedClosureTest$Pogo.doSomething(MemoizedClosureTest.groovy:12)
> at
> cern.ais.plugin.MemoizedClosureTest.testMemoizeFieldFromWithinClosure(MemoizedClosureTest.groovy:20)
> {code}
> Interestingly it works fine in the following cases:
> * Calling myMemoizedClosure just in the method not within the closure
> * Decalring myMemoizedClosure as a local variable
> * Having a non-memoized closure instead
> * Using {code}myMemoizedClosure.call('hello') {code} (my workaround)
> I tested it in two groovy versions I had around 1.8.9 and 2.1.9
