library initialization failed - unable to allocate file descriptor table - out of memory

After upgrading from Ubuntu 24.04 to 24.10, I get the following error message trying to launch xMage:

Googling turned up this old StackExchange thread: https://stackoverflow.com/questions/49435109/error-upon-jar-execution-unable-to-allocate-file-descriptor-table

And also this 4 month old reddit post about a user with a bleeding edge Debian system (likely comparable to Ubuntu 24.10) experiencing the same issue with a different .jar app: https://www.reddit.com/r/slaythespire/comments/1dgtkif/recent_trouble_launching_on_debian_resolved/

Unsure about how I can go about debugging this furhter, but very willing to do so if provided with instructions.

Looks like that bug was fixed for later java versions (xmage uses java 8 201):

So two workarounds possible:

1. Limit OS resources by special ulimit -n 10000 command, see your link;
2. Manually update launcher's java to newer version. You can try to use latest java 8 (no needs in additional settings -- just files replace in launcher/java folder) or any other java 9+ versions (see detailed instructions);
