Another problem (Java related?) is that, after a reboot, Mathematica
hangs on the first cell you execute (you can edit notebooks, but the
cell does not return a result).  Restarting Mathematica returns it to
its working state.  I think that Jon Fultz commented on this
previously in this forum.

You may also notice that starting up JLink can lead to a long error
message.  On the command line (not in a notebook, but in a terminal)
execute

Needs["JLink`"]

then execute

ReinstallJava[]

You will get a long list of messages starting with


Intentionally suppressing recursive invocation exception!
java.lang.IllegalStateException: recursive invocation
	at java.lang.ClassLoader.initSystemClassLoader(ClassLoader.java:1374)
	at java.lang.ClassLoader.getSystemClassLoader(ClassLoader.java:1357)
	at sun.security.jca.ProviderConfig$1.run(ProviderConfig.java:64)
        .....etc....




It appears that this is benign and is associated with Apple not
catching the message and suppressing its output to the console...
