Hi Windchillers,

We have a newly built Cluster for Windchill 9.1. Navigating through some of
Product#Folders were get the following error,

Could not initialize class
wt.epm.identity.EPMIconSelector$DocumentTypeIconSelector$DocumentTypeMapping

The Class file exists on all servers. We even tried to replace with an OOTB
class file. Ran Makejar.

It seems there is an issue with Tomcat not being able to execute this class.
I will appreciate some suggestions here. Below is the Catalina stack trace.

Caused by: java.lang.NoClassDefFoundError: Could not initialize class
wt.epm.identity.EPMIconSelector$DocumentTypeIconSelector$DocumentTypeMapping

This should be unrelated.

The key is to find the first NoClassDefFoundError or
ExceptionInInitializerError in a given process' logs. Occurrences after
the first contain less information (not our doing in this case, it's a
JVM thing).

Overall this is something to work through with technical support.

Thanks Jess, Bill and Alex for your replies.

We did more some intensive testing 'one slave at a time'. On one of the
slaves we got an error 'Could not map WTFolder to EPMDocument" (its not the
exact error but something like that). So we in all the logs and checked if
there we any issues related with EPMdocuments and found out that one Custom
OOTB type EPMCADDRAWINGTEMPL was surprisingly missing from the system. I was
surprised since we had upgraded the system 2 weeks back. Upgrade Manager did
not report this error too. After we propagated this type to all the machines
our issue was resolved.

Thanks and Regards,
Rohan
