Thread: Java binaries seem to ignore JAVA_HOME

I apologize for not picking a better topic, but this seemed the most fitting :D

I recently cross compiled openjdk11u to sparc64/linux. I needed to apply one patch for it to build, but the binaries seem to run fine. I tried compiling and running several different java programs I wrote.

However, when adding these binaries to PATH (java, javac, etc), they start to complain:

* Home for VM '' does not exist: 
* Invalid System VM:

However, I set the variable JAVA_HOME, and the output does not change:

echo $JAVA_HOME
/jdk/linux-sparcv9-normal-server-release/jdk
 
echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/jdk/linux-sparcv9-normal-server-release/jdk/bin
 
java -version
* Home for VM '' does not exist: 
* Invalid System VM: 
 
/jdk/linux-sparcv9-normal-server-release/jdk/bin/java -version
 
openjdk version "11.0.15-internal" 2022-04-19
OpenJDK Runtime Environment (build 11.0.15-internal+0-adhoc.rich.jdk11u-jdk-11.0.15-ga)
OpenJDK 64-Bit Minimal VM (build 11.0.15-internal+0-adhoc.rich.jdk11u-jdk-11.0.15-ga, mixed mode)

I have 0 idea on where to go next, I can't find a trace of an issue like this on the web.... am I correct that this isn't expected behavior?
