Bug 544897

Description Miroslav Zaťko 2019-02-27 15:46:50 EST

When Error log View is open and I am moving mouse pointer over the view, endless "Unhandled event loop exception" are thrown
It was even hard to get an exception stack from event log view as event log view itself throws the exception...

java.lang.NullPointerException
