Subject [jira] Commented: (HARMONY-3816) [drlvm][jitrino] BBP fails to provide safe-points on back branches from exception handlers
Date Fri, 04 May 2007 13:58:15 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-3816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12493691
] 

Mikhail Fursov commented on HARMONY-3816:
-----------------------------------------

Is there any testcase to reproduce the failure?
Something like endless loop with exceptions that won't be interrupted by Thread.interrupt
call?

> BBP makes wrong assumption regarding thread interruptability in dispatch nodes. Currently
implementation of exception dispatching mechanism doesn't provide safe points on exception
throwning thus BBP should forcibly insert safe-points on back branches from catch handlers.
The patch is attached.
