Viacheslav Kabanovich commented on JBIDE-11859:
-----------------------------------------------
ConfigureProblemSeverityMarkerResolution in constructor calls getPreferenceLabel(), which
finds WorkbenchPreferenceNode object, and calls createPage() on it in order to get that
label. After that the preference node keeps the reference to the page, but page's UI
is not created. When, after that the preference dialog is opened and some other page is
edited and OK is pressed, the dialog, looks for page reference in each preference node,
and if found, calls performOK() on it.
So, these steps provide high probability to reproduce the issue:
EXECUTE: Open a file with a CDI error/warning marker.
EXECUTE: Click on the marker to get quick fix list, and make sure that there is
'Configure Problem Severity' option.
EXECUTE: Open Preferences dialog.
EXECUTE: Modify anything on a page that is not relevant to the error marker mentioned.
EXECUTE: Press OK.
FAILURE: Exception listed in the description.
