Enums are not usable in mixed scala/java projects

[mushtaq]

Compiler version

3.2.1

Minimized code

See this github repo which uses 3 steps to reproduce it:

• Create a Scala enum
• Create a Java interface that references the Scala enum
• Print enum value from a main method a) directly b) via Java interface

Output

Red
null

Expectation

Red
Red

So Color.class has a private static initialiser which sets the static fields as copies from Color$.class, but it seems the private static initialiser is not invoked before JColor copies the field?

there seems to be no mention of a public access modifier for <clinit> in the jvm spec, and here, but perhaps that is a secret requirement, or maybe only affects specific jvm
