Attempts to run the HotJava1.0 browser (builds h thru j) with JDK1.1.1b fail.
If the above mentioned browsers are run with JDK1.1.1a, everything works "fine".

The problem typically occurs during or after the execution of the "What's Hot"
applet/welcome mat.
It's difficult to say exactly where the problem is. After a hang, a dbx stack
trace shows the following:

=>[1] _pause(0x6f9, 0x0, 0xef7b0c90, 0x0, 0xef55f6fc, 0xef782c7c), at 0xef4f5ba8
  [2] idle_thread(0xed599190, 0x0, 0xfffffff0, 0x1, 0x0, 0x0), at 0xef782c7c
  [3] start_func(0x1, 0xed599190, 0xef782c58, 0x0, 0x0, 0x0), at 0xef78e4d4

So possibly we're looking at a deadlock of some sort. Truss shows no
activity. The log file shows no exceptions were thrown at the time of
the hang.

One way to reproduce this is to remove $HOME/.hotjava/properties
first to clear any customization. Also be sure to unsetenv WWW_HOME
if set (since that overrides the default initial home page).

If removing .hotjava/properties is too painful, here are three
properties which should be set as follows (basically hotjava defaults):

hotjava.version=1.325, 02/18/97
hotjava.splash=true
home.url=doc:/lib/hotjava/whats-hot.html

This failure does not happen every time but it seems to happen
more reliably if the mouse cursor is in the middle of the hotjava
window. The whats-hot page is a big imagemap with applets that
do highlighting; so its possible that one of the applets is trying
to do something in response to the mouse cursor position while the
whats-hot.gif image is being loaded (just a thought).

Just to clarify versions. We copy over weekly builds from JavaSoft.

HotJava 1.0j -- built Feb 19 (same as /usr/local/java/hotjava1.0)
JDK1.1.1B -- built Feb 26 (same as /usr/local/java/jdk1.1.1)
JDK1.1.1A -- built Feb 19 (last weeks /usr/local/java/jdk1.1.1)

Per Tim's request here is the java trace when this deadlock occurs:
