'worker.config.json' configuration hardcoded for Windows

[shaunthomas999]

Current worker.config.json has windows specific environment variable reference because of which azure-functions-java-worker won't work in macOS (also in linux)

E.g., JAVA_HOME - referenced as %JAVA_HOME%

Repro steps

• Follow instructions in https://docs.microsoft.com/en-us/azure/azure-functions/functions-create-maven-intellij
• Worker won't startup properly while trying to run the application

Failed to start Worker Channel. Process fileName: %JAVA_HOME%/bin/java

Known workarounds

• Manually update worker.config.json file to have $JAVA_HOME instead of %JAVA_HOME%

Thank you so much for reporting this issue.

Actually, change %JAVA_HOME% to $JAVA_HOME didn't work for me eventually. I had to give full path to the java executable to make it work.

@amamounelsayed - Any idea when this issue will be fixed?

Can we change the title of this issue to worker.config.json configuration hardcoded for Windows?

Because this is preventing the worker from running on Linux and WSL (Windows Subsystem for Linux) besides macOS.
