To continue execution, breakpoint handler copies original instruction to special buffer and executes it. > When such instruction produces hardware exception, exception handler/signal handlers receive buffer address instead of original address and cannot detect code type correctly. So HWE in instrumented Java code is interpreted as HWE in native code. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
