Fix Version/s: 4.0.0-alpha-3
Resolution: Fixed
> Memoization doesn't seem to work for trait methods
> --------------------------------------------------
>
> Key: GROOVY-9901
> URL: https://issues.apache.org/jira/browse/GROOVY-9901
> Project: Groovy
> Issue Type: Bug
> Components: ast builder
> Affects Versions: 2.5.12
> Reporter: Lőrinc Pap
> Assignee: Eric Milles
> Priority: Major
> Fix For: 4.0.0-alpha-3

> Time Spent: 1h 10m
> Remaining Estimate: 0h

> I wanted to memorize a method in a trait, basically the following:
> {code:java}
> import groovy.transform.Memoized
> trait T {
> @Memoized
> double method() {
> Math.random()
> }
> }
> class A implements T {}
> class B implements T {}
> def a = new A()
> println a.method()
> println a.method()
> println new A().method()
> println new B().method(){code}
> And was surprised to see that they all returned different results.
> If this isn't supported, could we at least warn in case of AST
> transformations being applied to traits (i.e.
> [http://docs.groovy-lang.org/next/html/documentation/core-traits.html#_compatibility_with_ast_transformations)]?
