6.2.0.GA
Description
When operating BPMS 6.2.0 business-central Process Designer by 10 users (distinct users, different repositories, different processes), users face some issues:
- Process Designer itself isn't displayed ("Loading..." remains)
- Cannot save the process ("Loading..." remains)
- When opening an existing process, an empty process is displayed.
It's okay with 3 users but had the issues with 10 users.
In attached server.log, there were several Excpetions. Frequent one is org.uberfire.java.nio.file.NoSuchFileException and this JIRA focuses on this one.
