Chris Ochs created JRUBY-6475:
---------------------------------
Summary: md5 digest causes thread lock
Key: JRUBY-6475
URL: https://jira.codehaus.org/browse/JRUBY-6475
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.6
Reporter: Chris Ochs
Priority: Minor
Seems like the MessageDigest instance might need to be cached? Ran into this
when running an app that hits a cloud service that requires digest auth. When
it hits it's locking up 20% or so of our tomcat app threads.
