Description

import groovy.transform.Memoized

class Outer {
  private static class Inner {
    @Memoized
    static calc(int arg1, int arg2) { arg1 + arg2}
  }
}

println Outer.Inner.calc(3, 4)

Works with 2.4.12 but for 2.5+, results in:

groovy.lang.GroovyRuntimeException: NPE while processing ConsoleScript12
