java.util.ConcurrentModificationException error

[Beta User]

Hello,

I'm using springsource-ap-1.0.0.RC1 and found what is apparently a bug. When I deploy a PAR, it occasionally throws a java.util.ConcurrentModificationException error and fails to deploy. However, if I restart the platform or try to re-deploy the same PAR 3-4 times its succeeds.
I believe it might be something to do with the default timeouts to lookup services or something along those lines.

Here is the error stack when deployment of the PAR fails:

[2008-08-18 12:42:56.546] platform-dm-13 <SPDE0020E> Application context creation failure for bundle 'HelloWorld-1-com.springosgi.web'.

And like I mentioned, this error occurs some of the time, other times it deploys the same PAR with no issues.

Daniel,

This is almost certainly a bug. Can you create a JIRA issue (http://issuetracker.springsource.com/) attaching your trace and dump files please.

Rob,

Just curious, was this actually a bug ? I saw the JIRA issue with a resolved/fixed status but no comment.

I ask because I'm writing on the SpringSource-AP and have this as a sample application.

Wanted to see if I needed to change something in the application, or if this was a SpringSource-AP bug. And if its the latter, to ask if it will be corrected in the 1.0(final) release of SpringSource-AP, if not, so I can add a note indicating why the ConcurrentModificationException occurs.

Thanks,
Daniel

Daniel,

Rob's out today so I thought I'd answer this in his absence. Yes, it was a bug - thanks for bringing it to our attention. The fix will be included in the next 1.0 release.

Thanks again,
Andy
