Humm, there does seem to be something wrong here.
I would expect b to get set to "java0x3" (what a was set to).
Here is a really simple test case:
public class PrintString {
public static String foo(String s) {
return s;
}
}
package require java
set a [java::new String foo]
java::call PrintString foo $a
> foo
It should not work like that. The method
should just return javax0x1.
I have also added a test case for this problem to
the HEAD branch. The patch is as follows.

Of course, the problem still needs to be fixed, but now
that we have a test case it should be easy.
