failure without JAVA_HOME env var

[rdp]

In OS X, portable, works great with JAVA_HOME set, without it:

 % ./javaws.sh     /Users/packrd/Downloads/roll-gen.jnlp

What did you set your JAVA_HOME to start with? What is your reason for not setting JAVA_HOME? It seems ITW looks for jre to run the jnlp app first in JAVA_HOME. If JAVA_HOME is not set it tries to look for the jre in standard installation directories where one would install java. Do you have java installed at /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.302.b08-0.el7_9.x86_64/? Or where have you installed java on your machine?

I hadn't set it. It installs a java into /usr/bin/java so sometimes I don't end up "having" to set the environment variable.

$ ls /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el6_10.x86_64/jre/bin/java
ls: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.252.b09-2.el6_10.x86_64/jre/bin/java: No such file or directory
$ find / -name javac 2>/dev/null
/usr/bin/javac
/Library/Java/JavaVirtualMachines/amazon-corretto-8.jdk/Contents/Home/bin/javac
/System/Volumes/Data/Library/Java/JavaVirtualMachines/amazon-corretto-8.jdk/Contents/Home/bin/javac
# and some others from IntelliJ

Thanks!
