  • Did JBoss came up without errors ? Can you please attach a bigger snippet of log file?
  • Hi,

    what was the solution for this issue? We're getting the same error when trying to accept a task after upgrading from 7.8 HFA to HFD.

    I'll try resetting the analytics engine, but would be intersted to find out what you did.

    Thanks, Moritz
  • @nileshr @moritzw Did you find solution for this? Currently i am facing same issue and i came to this page after searching on forum. Any help is appreciated.
