scribing this issue in more details.

The test net001 will be available in the releases v14r12, v131r12 of testbase_nsk.

This bug affects also the following test from testbase_nsk:

nsk/hprof/options/net/net003

======================================================================


Name: egR10015 Date: 02/01/2002



Hprof agent shipped with HotSpot 1.4.0-b92 fails to pass the following test

nsk/hprof/options/net/net001

from testbase_nsk on Solaris/SPARC, Solaris/x86.
The reason is that profiled VM terminates with unexpected code 1 instead of
expected 95, though no crashes and/or no failures are observed. Note also
that unexpected exit code never happens on other platforms such as Linux
RH 6.2, Windows 2000.

The test checks that HPROF profiler agent will send profiling data over
a socket, specified by the option "net". It consists of the following
files.
net001.java contains a main class which starts profiled VM in a separate
process and a special thread collecting the data and writing it out to the
file net001.hprof.out.
net001p.java contains an auxiliary class used for profiling itself.

The problems also remains when profiled VM and server collecting the data
are run as two separate programs mutually independent from each other.
So, I suppose that issue is not in inorrectly working Java method
Process.exitValue().

To reproduce the bug run with HS1.4

sh doit.sh $JAVA_HOME

in
/net/sqesvr.sfbay/export/vsn/GammaBase/Bugs/<this bug number>

where JAVA_HOME should point to jdk1.4.0

There is also another problem which prevents the test from pass on Windows 2000.
It seems like Hprof or underlying network support abruptly closes socket stream
on that platform, and it leads to incomplete profiled data. I'm going to file
a separate bug de
