Crashes on Emacs master. exited abnormally with code 13

I am editing a simple Java for Android project, and (eglot-java-mode) does not even start.
Error buffer:

The errors that you're seeing don't seem to be related to eglot-java itself (eglot initialization and/or JVM crash).

• Generally speaking, I've seen similar messages when there are version incompatibilities between the installed Eclipse JDT LS server and an old Java version.
• Nowadays, it looks like the Eclipse JDT LS sever requires at least JDK 17 to run, per their project documentation.

Based on your logs, what I recommend is the following:

• I'd first try making sure that JDK17 is used, just to validate Java version compatibility issues
  • It does seem the JAVA_HOME sent to the LSP server is /usr/lib64/zulu-openjdk8 compared to the command-line starting the server itself... /usr/lib64/zulu-openjdk11/bin/java (2nd line of the log message in the jsonrpc request).
  • Then, if that works, I'd ensure that JDK17 is used for starting the language server, if I still need to specify zulu-openjdk8 for whatever reasons
• I doubt that emacs-master makes a difference
  • However, I don't run any emacs master/trunk software, because I don't read the mailing lists anymore for potential bugs, etc.
  • I do have one machine running emacs 29.1.90 (compiled from source) from the emacs-29 branch though
    • On that machine, my JDK is openjdk 17.0.9 (Ubuntu)
    • The installed Eclipse JDT ls server has version 1.31.0 (~/.emacs.d/share/eclipse.jdt.ls/.eglot-java-jdtls-version)
    • Essentially, no problems at all...

True. Updating java to 17 resolved the issue.

It is very user-unfriendly though, to not have an error message for such a simple case. But I guess this is Eclipse JDT's problem, not eglot-java's.
