Hello all!

Please review this change that would add facilities to help instrumentation of Throwables, to get a rough count of how many Exceptions and Errors an application has thrown during its lifetime. This can help developers and people working in customer-related support roles to do a high level assessment of a program to see if it has any undesirable patterns for instance. The instrumentation point will Receive the Throwable thrown, from which information about message and stack trace and throwable type can be extracted. Webrev: http://cr.openjdk.java.net/~nloodin/exception-tracing/webrev.01/ http://bugs.sun.com/bugdatabase/viewbug.do?bugid=8003322 Nils - you can explain why the byte code instrumentation can't be used here?
