> After install Netbeans 11.2
> ----------------------------
>
> Key: NETBEANS-3481
> URL: https://issues.apache.org/jira/browse/NETBEANS-3481
> Project: NetBeans
> Issue Type: Bug
> Components: ide - UI
> Affects Versions: 11.2
> Environment: Windows 7 Home Premium 64 bits, Sony Vaio, Intel Core2
> Duo P7450, 6GB
> Reporter: Daniel Caril Kogevnikovs
> Priority: Major
> Labels: beginner
> Attachments: messages.log, messages.log, messages.log.1,
> messages.log.2, metrics, uigestures, updater.log.0
>
>
> Immediately after installation, I created a project, java with Maven / Java
> Application. Netbeans started updating something and didn't finish, it froze.
> I canceled the session and without booting Win 7 Home Premium, I opened
> Netbeans again. The notification tab displays the message "Install nb-javac
> Library" and then a new message "unexpected Exception", and requests to be
> sent to Time Netbeans.
