UnsatisfiedLinkError on Mac OS X with Apple's Java 1.6

Submitted by vocaro on Tuesday, 27 May, 2008 - 09:30

I'm running Mac OS X 10.5.2 and have installed the new 1.6.0_05 release of Apple's Java distribution. The new Java seems to be causing problems, however, because jEdit 4.3pre14 will not run with it installed. I get:

java.lang.UnsatisfiedLinkError: /usr/lib/java/libObjCJava.A.dylib:

There has been talk of this bug in other places, namely here:

and here:

My guess is that the problem can be worked around by preventing jEdit's Mac OS plugin from launching, but I haven't confirmed this.

Any other thoughts?

jedit failure to startup on Mac OSX 10.5.5

I found on my Intel Mac 10.5.5 with the latest JEdit (as of 06 Oct 2008) that removing the Mac jar does not work for me, but opening the "Get Info" and setting to 32 bit mode for the Jedit application does work.

Good luck.

You can probably work around this for the time being by downgrading Java for jEdit.

I'll try to figure out exact steps when I get home, but if you explore the jEdit.app directory, I think you have to replace the JavaStub..... link with a one to one in your 1.5 installation directory (usually /System/Libary/Frameworks/JavaVM.Frameworks/....[get lost here from memory])

That might be /System/Frameworks. Take a look around, otherwise I'll try to remember to look around tonight.

Yes, jEdit will work with the previous Java 1.5 installation on OS X 10.5.2. I've confirmed this on another machine that did not have the 1.6 upgrade.

However, there is a less invasive workaround to get jEdit running on Apple's Java 1.6. Simply remove the Mac OS plugin. First, open the jEdit.app package and navigate to Contents/Resources/Java/jars. Next, remove the MacOS.jar file. jEdit will now launch without crashing, allowing you to keep Java 1.6 installed.

This confirms that jEdit's Mac OS plugin is indeed triggering the problem. Perhaps it can be modified in some way to workaround the crash.
