Mark Payne commented on NIFI-416:
---------------------------------
Right -- so in windows you can simply run "java" without explicitly adding the
".exe" but if you are going to do new File("java").exists() you will get false
without the ".exe".
Perhaps the easiest thing to do is just:
File javaExecutable = new File(... + "java"); // like you have it now
if ( !javaExecutable.exists() ) {
javaExecutable = new File(... + "java.exe" );
}
// continue with logic to check executable, etc.
> NiFi launcher does not respect JAVA_HOME, fails silently

> If you override your JAVA_HOME to another location, the nifi.sh script will
> use it, but the RunNiFi launcher will ignore it entirely. This results in a
> failure with no logging (even with verbose flag) if your default Java version
> is too old. See an example below
