Classic VMs (from 1.2 to Kestrel fcs) fail to pass the test below (return value is 97)
both on win32 and Solaris: signal raised with Signal.raise method is not handled by
a user-defined handler.
For instance:

$ java -classic -version
java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-A)
Classic VM (build 1.3.0-A, native threads, nojit)
$ java b4222557
$ echo $?
97

The test is passed by HotSpot VMs 1.3beta-C to 1.3beta-J, 1.0.1fcs-G on winNT
and by HotSpot 1.3beta-N on Solaris.
The test is failed by HotSpot VMs 1.3beta-K to 1.3beta-N on winNT and by
HotSpot 1.3beta-M on Solaris.
The test was developed as a regression test for the bug filed against
HotSpot 1.0_early_access:
#4222557 Synopsis: sun.misc.Signal does not work with HotSpot
(Integrated in releases: 1.0_rc2).
