[jboss-jira] [JBoss JIRA] Commented: (JBAS-3199) Tomcat consuming 99, 9% CPU

[Tim Dionne (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBAS-3199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12430242#action_12430242 ] 

Tim Dionne commented on JBAS-3199:
----------------------------------

Hi there --

I'm trying to find the subversion revision number that "fixed" this.  I don't see any bugs filed for the jdk, so I'm assuming that the fix was to not call Math.floor().  I looked in the tomcat and jboss svn repositories and I cannot find the fix.  Also, there are no subversion commits associated with this issue.  Can someone help me?  We currently use Jboss 4.0.4GA in our application, and upgrading to a later release is not as trivial as perhaps applying a patch to the jboss that we build.

Thanks in advance.
