using OpenJDK Windows binaries in WSL

1) install OpenJDK windows version

e.g. zulu versions
https://www.azul.com/downloads/?version=java-11-lts&os=windows&architecture=x86-64-bit&package=jdk-fx#zulu

• download .msi file, click and install (set PATH)

2) check intallation using Windows Powershell

java -version
javac -version

3) use Windows binaries in WSL

• set JAVA_HOME in .bashrc by adding a line of

export JAVA_HOME=/mnt/d/xxx/Zulu/zulu-11/bin/javafx/

• re-boot WSL, check by

java.exe -version
javac.exe -version

call java.exe instead of java in WSL since it's Windows binary (avoid installing another OpenJDK linux version)
