OWB mapping or process flow hangs while deploying

I faced an issue while deploying mappings and process flow in OWB 11.2.0.3.
Validation and generation end correctly, but when deploying , it just hangs.

OWB log file ([ORACLE_HOME]/owb/logs) showed following:

I unregistered and registered all locations used by the builder, but error continued to show up in logs and mappings continued not to deploy.

The issue was that OWBSYS password was changed. I altered the user to set the original password, with which workspace was created with, and deployments were successful
