Did you launch it from the Finder or from a terminal?

I have Java 1.5 installed, but I can't tell from within the app which JVM is being used.


I double-clicked the jar. So more a finder launch but I'm not really sure what other code is used to get it up and running. I'm also not really sure what determines the version used for double-clicked jars, most likely that info is in the list archives somewhere. How to setup to use 1.5 for command line and application bundles was recently discussed. 

But to determine what jvm is selected for double clicked jars you just need a manifest...

Manifest-Version: 1.0
Created-By: Launch Version Test
Main-Class: VersionChecker

For BBEdit I set to save as Unix. I still had to ensure the last line got a return character. One misstep.

Version checking code is simple.

public class VersionChecker {

public static void main(String[] args) {
System.out.println(System.getProperty("java.version"));
}
}

jar that...
jar -cvfM version.jar VersionChecker.class META-INF

-m usage wasn't working, another misstep, I just now notice it was saying the manifest file wasn't there for some reason. There were a few other missteps and typos but even given that, it doesn't take long to get a working test to tell you what jvm version is used.

1.5.0_06

For me. 
There's nothing wrong with a editor and Terminal for quick and dirty testing.
