Trusted Applications + Bouncy Castle + BigInteger = trouble?

Sergey Svishchev

Has anyone seen the condition when threads in an Atlassian app spin this way (eventually consuming all available CPU and/or thread pool)? If so, have you resolved it?

Doesn't seem to matter much where the TA library is called from; a good combination is JIRA + FishEye plugin.

Same problem here while Confluence 5.2.3 is trying to communicate with Jira 5.2.7. We did recently update our JDK from jdk1.7.0_25 to jdk1.7.0_51, could this be a problem?

We see also these exceptions:

ERROR [ajp-exec-14] [confluence.extra.jira.StreamableJiraIssuesMacro] logStreamableError Unable to render JIRA issues macro, connection to JIRA has been timeout.
