This weblog has moved to http://weblog.ikvm.net/

I did lots of work on exception handling. Most of it now works (fully compatible with J2SE 1.4). Some highlights: java.lang.Throwable is remapped to System.Exception (for maximum compability with .NET code) Throwable.getMessage(), Throwable.getCause() & Throwable.toString() all work, and are fully compatible with J2SE 1.4. Additionally, the message is stored as the System.Exception.Message property, and when the exception object was constructed with a cause, the System.Exception.InnerException property is set. Stack traces now work (fully Java compatible), except for J2SE 1.4 inner exceptions stack trace dumping. I made the XML remapping language more powerful. It now supports calling helper methods and using locals to twiddle around with method arguments. Things that don't work: When .NET code prints a stacktrace from an exception thrown by Java code, the stacktrace only shows the stack from the last rethrow point in the Java code. Throwable.printStackTrace() doesn't yet support Caused by: in the stack traces. Additional exception information object (that contains the stacktrace and the cause)  is not yet garbage collected when the exception goes away. Here is the testcase I used. Updated the snapshot. 6:32:54 PM    Comments
