Provide a way to disable embedded JRE
See original GitHub issueThe embedded JRE assumes a traditional FHS directory structure on Linux. Nontraditional distributions, like NixOS, do not have directories like /lib and so the embedded Java executable cannot be used. The following opaque error occurs when opening a Java file on NixOS:
no such file or directory: /home/user/.vscode/extensions/redhat.java-1.2.0/jre/17.0.1-linux-x86_64/bin/java
The file exists, but it requests a nonexistent interpreter, /lib64/ld-linux-x86-64.so.2. Deleting the jre directory allows me to use the extension, but that is an unpleasant user experience. A setting to ignore the embedded JRE would be appreciated.

Next version 1.3.0 will have a new setting “java.jdt.ls.java.home” that allows you to use a different JDK to start Java extension.
Another idea I had was that we could detect if the underlying Linux distribution follows the traditional FHS and automatically disable the embedded JRE if it is running on a non-FHS distribution.
Update: We can try to run the command “java -version” using the embedded JRE executable, and if it fails, disable embedded JRE.
