Re: Got an IllegalStateException: unread block data  while Querying on WTPart

Hi Jess,

In my case the client and the server are one and the same. Using API, I am attempting to read one EPMDocument number at a time from a .txt file and deleting that EPMDocument (and all objects in its ReferencedBy and UsedByReference list). For most EPMDocuments, the deletion is working fine. For about 1 in 500 EPMDocuments, we are facing IllegalStateException

Exception in thread "main" java.lang.IllegalStateException: unread block data

and that is interrupting the execution. I was wondering if we could catch this exception so that the program continues to run. We have attempted using try..catch, throws, https://support.ptc.com/appserver/cs/view/solution.jsp?n=CS72059, using UTF-8 explicitly instead of ANSI and using FileReader instead of InputStreamReader

Thanks so much,
