Build failure on Linux system with JDK 22-ea installed: Error in int: invalid base-10 literal: "22-ea"

[yesudeep]

Hello,

My system version of the JDK upgraded to 22-ea on Fedora Linux 39 (Workstation Edition), and that appears to break rules_jvm_external.

zsh❯ java --version
openjdk 22-ea 2024-03-19
OpenJDK Runtime Environment (Red_Hat-22.0.0.0.36-1) (build 22-ea+36)
OpenJDK 64-Bit Server VM (Red_Hat-22.0.0.0.36-1) (build 22-ea+36, mixed mode, sharing)

zsh❯ which java
/usr/lib/jvm/java-22-openjdk/bin/java

Here is the error:

Temporary workaround for those affected:

1. Install JDK 21: sudo dnf install java-21-openjdk

2. Use env JAVA_HOME=/usr/lib/jvm/java-21-openjdk-21.0.2.0.13-1.fc39.x86_64 bazel build ...
