Headless Java workspace cannot build (dies in javac, specifically building Swing).

This did not happen before 5/8.
The workspace can be found at :

/net/jano/export/disk03/awt/martak/headless/

This is happening in both Win32 and Solaris, in multiple places.

Stack trace is:

------

The following test case shows the problem clearly:

class A1 {
    A1() throws RuntimeException {}
}


class A {
    A1 bar = new A1() { };
}
