ConcurrentModificationException in CacheMap.clear
-------------------------------------------------
Key: JRUBY-1278
URL: http://jira.codehaus.org/browse/JRUBY-1278
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.x
Environment: JRuby trunk (rev 4178)
JVM 1.6.0-b105
Ubuntu 7.0 desktop
PetStore Rails app : http://tw-commons.rubyforge.org/svn/trunk/ : rev 21
Reporter: Alexey Verkhovsky
Assignee: Thomas E Enebo
Priority: Critical
Trying to run PetStore from tw-commons under Mongrel sometimes (about once in
five attempts) throws a ConcurrentModificationException, even before clashing
with JVM over handling SIGUSR1 (c.f. http://jira.codehaus.org/browse/JRUBY-1277)
Since it doesn't always happen, this is pretty hard to reproduce.
Here is the stack trace:
=> Call with -d to detach
=> Ctrl-C to shutdown server
