Cool! Its good to have someone pushing for features needed by other projects. > This piece causes no errors on the commercial JVM's (sun's jdk 1.3.1 > & 1.4), so apparently there's something missing in Kaffe. Any idea > what it is, and what I could do about it? That is odd. I don't think anything interesting has happened in recent JDKs with support for Cloneable, so I doubt that's the real problem... You're sure that "MediaserverFiler$Group" is really Cloneable? (Perhaps the error is elsewhere, and other VMs never try to clone this class?) Invoking clone via reflection is a bit odd, I'd guess the reflection support is more likely the culprit. (Making a smaller test case based around this idea might pan out.) The clone native method is pretty simple (see libraries/clib/native/Object.c). Could you run kaffe under GDB (see FAQ.debugging) and put a breakpoint on the SignalError() call in clone to see what the object really is? (developers/gdbinit contains a gdb macro 'pobject' that might help.) Technically, the NotCloneable exception should be wrapped because it occurs in a reflection invocation (I bet the jython code is just unwrapping that). But, just in case, you might run with '-vmdebug ELOOKUP' (assuming Kaffe was configured with --enable-debug) to see what exceptions are really being thrown/caught. > If there's not enough info about the problem here, please ask for more. The relevant source bits of this function might be useful: org.python.core.PyReflectedFunction.__call__(PyReflectedFunction.java:line unknown, pc 0x854dee1) Has anyone else out there tried jython and (CVS) Kaffe? The jython web pages talk about a Kaffe that doesn't support java.math.BigInteger, but I know that's there now (so I assume that note is really old). -Pat ----- ----- ---- --- --- -- - - - - - Pat Tullmann [EMAIL PROTECTED] Never ascribe to malice that which can be explained by incompetence. _______________________________________________ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
