[jira] Commented: (HARMONY-5534) [drlvm] RecursiveTest failure from the reliability test suite

["Pavel Rebriy (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HARMONY-5534?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12583573#action_12583573 ] 

Pavel Rebriy commented on HARMONY-5534:
---------------------------------------

After a deep investigation I've found the root of the problem:
The problem is in pthread_kill() function. The function sends the signal to a given thread. If a given thread could not be found pthread_kill() returns ESRCH error. This is in theory, in practice pthread_kill() doesn't perform thread validation check and crashes in case illegal thread argument.

This is known behavior of  pthread_kill() and it does so for performance reasons.

I'm going to fix the pthread_kill() call to perform thread validation check before the function execution.
