Eric Milles updated GROOVY-11843:
---------------------------------
Description:
Consider the following:
{code:groovy}
@CompileStatic test() {
new Pogo(a:1, b:2, c:3)
}
{code}
When "a", "b" and "c" map to "setA(int)", "setB(int)" and "setC(int)"
respectively there are spurious {{ACONST_NULL}} and {{POP}} instructions
generated after each setter invocation.
