Ulrich Mayring created NETBEANS-5177:
----------------------------------------
Summary: Crash: cannot get exclusive access to uihandler.properties
Key: NETBEANS-5177
URL: https://issues.apache.org/jira/browse/NETBEANS-5177
Project: NetBeans
Issue Type: Bug
Affects Versions: 12.2
Reporter: Ulrich Mayring
Attachments: sc.png
I experienced a number of total freezes after installing NB 12.2 (have been
using 12.0 before), but could not get an error message of any sort, since NB
was completely unresponsive to keystrokes or mouse. This changed today, I got
an error popup, which I attach. NB was again totally unresponsive, but I could
make a screenshot of the popup message.
The black shadow around the error dialog actually is tens or hundreds of the
same popup windows behind the first one. They keep piling up at CPU speed until
the app runs out of memory or is killed. For a while I could close a few of
them, but they kept coming up faster than I could click.
The file in question (see screenshot) looks normal to me. It has the correct
owner and permissions and its content is this:
count=1000
MTTF=71985
uihandler.preferences.writable.check=1608633016127
The crash happened directly after starting the IDE, while it was reading in the
last project I worked on. No user interaction was involved.
