Eric Milles updated GROOVY-11872:
---------------------------------
Affects Version/s: 4.0.30
> SC: compile static method and default parameter values
> ------------------------------------------------------
>
> Key: GROOVY-11872
> URL: https://issues.apache.org/jira/browse/GROOVY-11872
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation
> Affects Versions: 4.0.30, 5.0.4
> Reporter: Eric Milles
> Assignee: Eric Milles
> Priority: Major
> Fix For: 5.0.5
>
>
> Consider the following:
> {code:groovy}
> class Foo {
> @groovy.transform.CompileStatic
> void bar(List list = baz()) {
> for (item in list) {
> println item
> }
> }
> List baz() {
> ['fizz','buzz']
> }
> }
> new Foo().bar()
> {code}
> The generated method {{bar()}} gets the {{CompieStatic}} annotation, but when
> classgen comes around, the direct method target to {{baz()}} is instead
> written as an invokedynamic instruction.
> Actual bytecode:
> {code}
> // Method descriptor #15 ()V
> // Stack: 2, Locals: 1
> @groovy.transform.Generated
> public void bar();
> 0 aload_0 [this]
> 1 aload_0 [this]
> 2 invokedynamic 0 invoke(Foo) : java.lang.Object [79]
> 7 checkcast java.util.List [31]
> 10 invokevirtual Foo.bar(java.util.List) : void [81]
> 13 return
> {code}
> Expect bytecode:
> {code}
> // Method descriptor #15 ()V
> // Stack: 2, Locals: 1
> @groovy.transform.Generated
> public void bar();
> 0 aload_0 [this]
> 1 aload 0 [this]
> 3 invokevirtual Foo.baz() : java.util.List [68]
> 6 checkcast java.util.List [31]
> 9 invokevirtual Foo.bar(java.util.List) : void [70]
> 12 return
> {code}
