What is the expected output? What do you see instead?

No splash screen or icon on the doc, app closes silently.

Running the jpf-boot.jar directly from within the lib dir a window opens
(java -jar jpf-boot.jar)

Application Start Failed

Error:Java.Lang.IllegalArgumentException: unknown plug-in ID: - null

can any other mac users confirm this?

try running java -jar lib/jpf-boot.jar from within the ntorrent dir, not the 
lib dir.

Error:Java.Lang.IllegalArgumentException: unknown plug-in ID: - null
this error is cast when it can't find the plugins.

here you can create your own app file.

It seems to crash as described.
But doing java -jar lib/jpf-boot.jar from Resources/Java dir it works.

Just change java Version in Info.plist to 1.6+ will fix this issue.

after line :      <key>JVMVersion</key>
--      <string>1.5+</string>
++      <string>1.6+</string>

Attached is the correct Info.plist. And a working copy of the app

this fix will force the use of java 1.6? so this really isn't a work around for 
those
with java 1.5... or am i wrong?

To reproduce this crash you must have a OSX system updated with  Java for Mac 
OS X
10.5 Update 2.
Earlier versions of java for mac will not be able to reproduce this crash.
Another work around is to write absolute paths in Info.plist. 

It seems that version of Java5 after update erase $JAVAROOT after follow
JavaApplicationStub symlink. After that $JAVAROOT/lib/commons-logging.jar 
becomes
/lib/commons-logging.jar.

Here is some info.

ken/
and another ugly work around (delete symlink and copy JavaApplicationStub to
Contents/MacOS)

did change to info.plist and can confirm it fixes the crash issue on 2 seperate 
systems.

thanks for the quick workaround.
