How do I install Java JDK? ("Exec format error")

Hello,

I am trying to use the Java JDK in a "Docker-OSX" based image. I have unpacked and started the OpenJDK, but I get:

sh-5.1$ ./jdk-19.0.2.jdk/Contents/Home/bin/java
sh: ./jdk-19.0.2.jdk/Contents/Home/bin/java: cannot execute binary file: Exec format error

(I also tried the Oracle JDK, with the same result).

I am using Windows 10 on an Intel 64 bit environment with WSL2.
