This looks similar to, and might be a duplicate of, bug 364048.

Please have a look at bug 364048 comment 3 to see if it applies to you.
Comment 3 eg.trab CLA 2011-11-20 19:33:07 EST 
no, we do not use the osgi.classloader.singleThreadLoads=true option.
Comment 4 Thomas Watson CLA 2011-11-21 14:26:29 EST 
From the looks of the screenshot this looks more like a problem because of the coarse grained locking we must do on pre-Java6 VMs.  This should be fixed when running on Java 7.
