FULL PRODUCT VERSION :
java version "1.4.1-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-beta-b14)
Java HotSpot(TM) Client VM (build 1.4.1-beta-b14, mixed mode)

FULL OPERATING SYSTEM VERSION :
glibc: glibc-2.2.5-34
kernel: Linux NetworkTester2 2.4.18-3 #1 Thu Apr 18
07:37:53 EDT 2002 i686 unknown
distribution: Red Hat Linux release 7.3 (Valhalla)


A DESCRIPTION OF THE PROBLEM :
When you launch a process to execute a (bash) shell script
on Linux, if the script uses the "exit" command to return
its exit status, that status is not returned by
Process.waitFor() correctly (as it does w/ previous
JREs). Appears to be returning 0 almost always.

REGRESSION. Last worked in version 1.4

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Place Test.class and test.sh in same directory.
2. Execute the Test class
3. See the results
