NPE at Connection Shutdown
--------------------------
Key: JRUBY-2425
URL: http://jira.codehaus.org/browse/JRUBY-2425
Project: JRuby
Issue Type: Bug
Components: ActiveRecord-JDBC
Environment: JRuby 1.1.1/AR-JDBC 0.8
Reporter: Peter K Chan
I am getting occasional NPE while running my unit tests. I don't have a
reproducible test case (it happens occasionally), but by the look of the site
of exception, it looks like it may be fixed just be looking at the code. I
don't know enough of the internals to be able to fix it myself, but I am hoping
that someone who knows can use the NPE report to figure out where the bug is.
Exception in thread "Tasker" java.lang.NullPointerException
