Description

GParallelizer – rapidly being rebranded as gpars – has a
small problem with generics in a Groovy file. The code base has lots of
uses of generics in both Java and Groovy code. One class however
(src/main/groovy/org/gparallelizer/actors/pooledActors/Safe.groovy) will
not compile using Groovy's FileSystemCompiler, but it compiles fine
under IntelliJ IDEA. The errors are:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
/home/users/russel/Repositories/Bazaar/SharedRepositories/GParallelizer/Working/src/main/groovy/org/gparallelizer/actors/pooledActors/Safe.groovy: 112: unable to resolve class T
@ line 112, column 7.
T result = null
^

lock.withReadLock

{ result = copy(data) }

return result

3 errors

but these are not the only uses of generics in the class, yet only these
cause problems. As noted about there are other uses of generics in
other Java and Groovy files but only the three message above are issued.
