Can you attach messages.log file, located in your userdir - subdirectory var\log, please? This exception is caused by corrupted mdr storage. As a workaround, you can delete the whole var\cache\mdrstorage directory (again, located in your netbeans userdir). After that, restart the ide, mdr storage will be build again and the exception will disappear. Is this issue reliably reproducible? If so, it would be helpful if you can provide a description of steps that led to this exception. Or possibly, did you experince any crashes of the ide (including any abnormal exit) or OS? The report does not contain any justification why this should be P1 neither P2 bug, decreasing priority to P3.
