[jira] Commented: (SUREFIRE-754) unbounded memory use when capturing logs

["Kristian Rosenvold (JIRA)" <ji...@codehaus.org>]

    [ https://jira.codehaus.org/browse/SUREFIRE-754?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=271994#comment-271994 ] 

Kristian Rosenvold commented on SUREFIRE-754:
---------------------------------------------

The interesting thing about this issue is that is has switched VM in 2.9. In previous versions you'd be tweaking argLine on the forked jvm to allocate more memory, whereas now the buffer usage is within the surefire plugin itself, meaning you have to tweak MAVEN_OPTS to get more memory.

I will try to fix the underlying problem, just figured you'd like to know this workaround as of now.
