["Tibor Digana (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SUREFIRE-1808?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17143896#comment-17143896 ] 

Tibor Digana commented on SUREFIRE-1808:
----------------------------------------

In case of OOME you must not rely on stack trace that the particular line has OOM.
The JVM is used to throw it several times and finaly the it thrown from anywhere.
It does not have to be related to the line.

You are using very old version. Plse switch the version to {{3.0.0-M5}} and let us know what you have observed.
