Hello!

After having "installed" Rhino 1.5r4 on my system, many of my old
Rhino scripts fail to run any longer. Reason: Java class lookup seems
to be broken!

Here are some facts:
 - Java classes and interfaces within JAR files or directory trees
   (within my "ClassPath") are no longer found - although they are
   definitely present
 - unpacking JAR files (or moving directory tree contents) into a
   folder such as $JavaHome/jre/lib/classes solves the problem -
   however, I would even have to unpack the Rhino library (js.jar) 
 - going back to Rhino 1.5r3 immediately solves the problem as well
 - I'm currently running Sun JDK 1.4.0_03 - but the problem exists
   as well under 1.4.0_02, 1.4.0_01 and 1.3.?_06 (don't remember the
   version number) I already had a similar problem with "BeanShell"
   (www.beanshell.org) and JDK 1.4.1 a few weeks ago - I then deci-
   ded to go back to 1.4.0_03 as this solved most of the problems.
   Later, a colleague ran into similar class loading problems and
   had to go back to 1.4.0 as well...(very strange)
 - I'm running Win98SE, she was running WinXP Professional

Did you work on class loading between Rhino 1.5r3 and 1.5r4?

Do you have any idea why class loading breaks - presumably as soon as
somebody tries to use his/her own class loader (I know that BeanShell
is doing so, but
Rhino?)?

Thanks in advance for any help!
