Cannot set JAVA_HOME via LSEnvironment

[kiwicodemonkey]

I'm submitting a…

• bug report

Short description of the issue/suggestion:

Setting JAVA_HOME via the LSEnvironment key in Info.plist is not recognised when running universalJavaApplicationStub.

Steps to reproduce the issue/enhancement:

1. Add following to plist:

		<key>LSEnvironment</key>
		<dict>
			<key>JAVA_HOME</key>
			<string>Contents/Plugins/zulu-8.jre/Contents/Home</string>
		</dict>

2. Run app

What is the expected behavior?

Application launches and runs

What is the current behavior?

Script complains that no java environment is found.

Please tell us about your environment:

• universalJavaApplicationStub version: 3.2.0
• macOS version: Big Sur 11.2.3 (M1)
• Java version(s): zulu8.52.0.23-ca-jre8.0.282-macosx_aarch64

Other information:

If I edit the script and set JAVA_HOME, the application launches and runs fine.

Sorry for my delayed response.

Can you open the Console.app (not Terminal!) and set a filter/search for syslog and then launch your app. You will find a bunch of log messages from the stub in the Console.app window. Please select all and copy them here so I can assist you any further...

Unfortunately, I'm not able to reproduce the issue. This is my output with a test app:

My system:

• universalJavaApplicationStub: 3.2.0
• macOS 11.2.2 (Intel)

I cannot test on an M1 though, but I'm pretty confident this doesn't relate to the processor architecture.

Are you sure you're really using universalJavaApplicationStub v3.2.0? There have been issues with Big Sur support in earlier versions which resulted in the console output you pasted here (especially found JVM: :/bin/java) which are resolved in 3.2.0 (refs #100).

Although it doesn't relate to the original problem (that Apple's App framework obviously does not export the JAVA_HOME variable), can you please share the output of the following command with me, so I can debug the afore mentioned issue regarding the found JVM: :/bin/java log entry:

/usr/libexec/java_home --xml

FYI: If you edited the Info.plist file manually and just start the app again with a double click from the finder, in some situations the App cache serves an old version of the app. You can try to come over this by renaming the app folder or incrementing the app version in Info.plist.

@karokhaziz as I wrote above: In this certain case I wasn't able to reproduce the issue and setting JAVA_HOME via the LSEnvironment key worked for me in the exact way @kiwicodemonkey wrote in its initial posting.

Is your log output the same as @kiwicodemonkey's?

That's most likely a cache issue, as I wrote above:

FYI: If you edited the Info.plist file manually and just start the app again with a double click from the finder, in some situations the App cache serves an old version of the app. You can try to come over this by renaming the app folder or incrementing the app version in Info.plist.

Or you can copy the app to another directory and rename it. This should also start the app with a clean cache...
