This is a problem because of relative paths, since we can't set JAVA_HOME
to the same place for everyone.
If I managed to put the entire folder of JRE inside the lib/aarch64/
It would be like so:
lib/aarch64/jre
lib/aarch64/jre/lib...
lib/aarch64/jre/bin...
So what would need is that to change the code in bdj.c in that if
(!java_home) statement
If it's not set open it one level up.
dl_dlopen without any additional instructions opens:
lib/aarch64/ the way it is now.
So, it needs to go a few folders deeper and go into
lib/aarch64/jre/lib/aarch64/server/ and libjvm.so will be here.
IF I managed to insert the entire folder inside libs.
