Confirmation Dialog is broken - at least for NB 12.2 / JDK 15 on Windows 10

[gtsh]

After toggeling 'Show confirmation dialog before adjusting the line endings' in the configuration, the dialog indeed showed up, - but was devoid of any controls, not even allowing to be closed by clicking into the x or using ALT-F4. Since it is also modal, this left no other option as to kill Netbeans using the taskmanager, and deselecting the option.

Found a way to fix it, but still, this is weird:
As it turns out, this somehow hinges on using jaxb-api-2.2.3.jar and jaxb-impl-2.3.0.1.jar. But early in the NB startup; you see something like this:

... indicating that the jar isn't there!
Fixing this, by actually placing it there, and afterwards, doing the same with the also missing impl, actually fixes the problem with the dialog too.

So it seems, there is actually something broken with the installation.
To be frank, I noticed problems with those two jars already in all versions starting from NB 9, breaking the installation of various plugins. So this might be a generall problem.

[gtsh]

Also note, that NB actually has jaxb-api.jar and jaxb-impl.jar, but residing in ide/module/ext/jaxb/... and of a more recent version. For me, using mklink to create hard links to those from extra\modules\ext did the trick without adding additional jars.

Don't now whether this will wreck havoc elsewhere though...

[junichi11]

I'll have a look at it later. Thanks for reporting it.

[junichi11]

Could you please try to use the dev version(0.9.0.1-dev)? : https://github.com/junichi11/netbeans-change-lf/releases/tag/v0.9.0

@gtsh
If it's an IDE problem, please report it to the JIRA :) Thanks.

Can you give the exact locations where I need to paste both the jars
