At random moments(as far as i can tell) we get "NullPointerExceptions" in several of our Tersus-applications. The client receives a "processing error", but is able to keep using the application without further problems.
Can you give me some hints how to troubleshoot this problem?
We are using Tersus 1.0.44 on tomcat 5.5.26
log example:
