Problems with 4.3.4f1 AndroidPlayer JAR file

When I try to compile my plugin with the new JAR file for the Unity AndroidPlayer for version 4.3.4f1, I get errors with javac trying to find that player. If I try to list the contents of the AndroidPlayer, it seems to indicate that the file is corrupt. This used to work with 4.3.1. Here is the output from that attempt to list the contents:

Code (csharp):

1.  
2. eds-mac-pro:Android ed$ jar -tf "/Volumes/Macintosh\ HD/Applications/Unity/Unity.app/PlaybackEngines/AndroidPlayer/bin/classes.jar"
3. java.util.zip.ZipException: error in opening zip file
4.     at java.util.zip.ZipFile.open(Native Method)
5.     at java.util.zip.ZipFile.<init>(ZipFile.java:128)
6.     at java.util.zip.ZipFile.<init>(ZipFile.java:89)

8.     at sun.tools.jar.Main.run(Main.java:222)
9.     at sun.tools.jar.Main.main(Main.java:1147)
10.  

Any ideas?

Thanks in advance,
