[core] ExceptionInInitializerError causing NetBeans not to start

[Allan Lykke Christensen]

Hi y'all,

I'm wondering if anyone has had the problem of getting an
ExceptionInInitializerError when starting NetBeans. It happened after
I installed a bunch of plug-ins.  The error is causing that I can't
start NetBeans at all. Anybody got a work around or do I need to clean
my userdir?

This is the module that causes your problem.
Remove that module (either by removing the jar in $USERDIR/modules
or by setting $USERDIR/config/Modules/the-module-code-base.xml's
<param name="enabled">false</param>

Thanks Petr,

I solved it by removing the "User Tasks" module. However, I'd love to
get the module working again as it was one of my favourite modules.
Not sure which module it is clashing with - anyway to easily determine
the dependencies of each module so that I can disable the other
modules?

Kind regards,
 Allan
