[I] Unable to verify plugins, then freezes [netbeans]

Soniflare opened a new issue, #9471:
URL: https://github.com/apache/netbeans/issues/9471

   ### Apache NetBeans version
   
   Apache NetBeans 30
   
   ### What happened
   
   Okay, so first off, I'm trying to install some old plugins to add Java ME (Micro Edition) support (I'm trying to program stuff for blu-rays...it's a long story).  I have all the required plugins for this added to the Downloaded page, yet when I go to install them, I get this error:
   `Cannot complete the validation of downloaded plugins`
   
   `The validation of downloaded plugins cannot be completed, cause: NBM
   /home/<homefolder>/.netbeans/30/update/download/org-netbeans-modules-javame-devicemanager.nbm needs unpack200 to process following entries:
   netbeans/modules/org-netbeans-modules-javame-devicemanager.jar.pack.gz`
   
   I don't know what this "unpack200" is, nor where to get one.  Is this a bug or am I just stupid?
   
   ### Language / Project Type / NetBeans Component
   
   Plugin Manager
   
   ### How to reproduce
   
   Download the plugins I'm trying to install:
   - [GitHub.com/lqthanh/j2me-archive](GitHub.com/lqthanh/j2me-archive)
   - [GitHub.com/BackendJava/Plugins-para-Reportes-en-java](GitHub.com/BackendJava/Plugins-para-Reportes-en-java) (just for the one plugin contained therein)
   - [Oracle.com/java/technologies/sdk-downloads.html](Oracle.com/java/technologies/sdk-downloads.html)
   
   Attempt to install them.
   
   ### Did this work correctly in an earlier version?
   
   No / Don't know
   
   ### Operating System
   
   Linux Mint 22.3
   
   ### JDK
   
   JavaMEv8.3.1 (or trying to, at least, I haven't gotten to that part yet)
   
   ### Apache NetBeans packaging
   
   Other
   
   ### Anything else
   
   _No response_
   
   ### Are you willing to submit a pull request?
   
   No

   To be more clear on the Apache NetBeans packaging field in this page, I used the Codelerity packages that have an installer.  Specifically the .deb one.

   Okay, nevermind.  I just found out that I can just tell it to use the jpackage file instead of unpack200 lol

   From what I can see on the Oracle.com website, it seems unpack200 is some kind of command that turns a packed file into a .jar file?
