GUI not showing up

[Zorgatone]

I try executing "java -jar BON-2.4.0.15-all.jar" on windows 10 and tried both with java 8 and java 18, but the GUI is not showing up (and no errors either) it hangs forever without doing anything.

The only output to the console is this:

Bearded Octo Nemesis v2.4.0.15 by Parker8283. BON v1 by immibis.
No arguments passed. Launching gui...

I had the same thing but I had an error after:
Bearded Octo Nemesis v2.4.0.CUSTOM by Parker8283. BON v1 by immibis. No arguments passed. Launching gui... java.lang.NumberFormatException: For input string: "stable_11" at java.lang.NumberFormatException.forInputString(NumberFormatException.java:65) at java.lang.Integer.parseInt(Integer.java:580) at java.lang.Integer.valueOf(Integer.java:766) at com.github.parker8283.bon2.data.MappingVersion.compareTo(MappingVersion.java:82) at com.github.parker8283.bon2.data.MappingVersion.compareTo(MappingVersion.java:7) at java.util.ComparableTimSort.countRunAndMakeAscending(ComparableTimSort.java:325) at java.util.ComparableTimSort.sort(ComparableTimSort.java:202) at java.util.Arrays.sort(Arrays.java:1312) at java.util.Arrays.sort(Arrays.java:1506) at java.util.ArrayList.sort(ArrayList.java:1464) at com.github.parker8283.bon2.util.BONUtils.buildValidMappings(BONUtils.java:65) at com.github.parker8283.bon2.gui.RefreshListener.mouseClicked(RefreshListener.java:34) at com.github.parker8283.bon2.BON2Gui.<init>(BON2Gui.java:108) at com.github.parker8283.bon2.BON2$1.run(BON2.java:118) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:311) at java.awt.EventQueue.dispatchEventImpl(EventQueue.java:758) at java.awt.EventQueue.access$500(EventQueue.java:97) at java.awt.EventQueue$3.run(EventQueue.java:709) at java.awt.EventQueue$3.run(EventQueue.java:703) at java.security.AccessController.doPrivileged(Native Method) at java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:74) at java.awt.EventQueue.dispatchEvent(EventQueue.java:728) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:205) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:116) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:105) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:101) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:93) at java.awt.EventDispatchThread.run(EventDispatchThread.java:82)

Fixed it by changing in com.github.parker8283.bon2.data.MappingVersion, line 70 and 71 the zeroes by v1.lastIndexOf('_')+1 (with v2 respectively), and I also deleted mcp_stable_nodoc (downloaded from https://github.com/ModCoderPack/MCPMappingsArchive)because the elongated name gave me other errors after this fix. Now I can finally open BON2 again and deobfuscate. I compiled the jar and put it in libs.zip if you are lazy to compile it yourself, see if it fixes anything.

I have no issues with https://github.com/LexManos/BON2, but it's only from 1.12 up
