This looks to be broken in 1.4.2-b19 build with latest CTRL+C changes. May be a regression.

Name: nt126004 Date: 03/31/2003


FULL PRODUCT VERSION :
java version "1.4.0_01"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.0_01-b03)
Java HotSpot(TM) Client VM (build 1.4.0_01-b03, mixed mode)


FULL OS VERSION :
Linux (SuSE 2.4.18-4GB)
SunOS 5.9

A DESCRIPTION OF THE PROBLEM :
When executing a process with Runtime.getRuntime().exec() in a linux or solaris environment, if the parent process is running in foreground and you hit 'Ctr-C' both processes are terminated, although this doesn't happen if the father process is killed by sending any of SIGKILL, SIGINT or SIGTERM signals

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
-Compile and execute the attached code without any arguments
-Check with ps that there are two processes
-Send a kill -2 (SIGINT) to the parent process (the same can be tested with SIGKILL, SIGQUIT and SIGTERM)
-Verify with ps that the child is still running (proper behaviour)
-Kill the children process
-Execute the father again
-Verify both processes are created
-Having the father process in foreground, hit Ctrl-C

EXPECTED VERSUS ACTUAL BEHAVIOR :
The child process should keep running
Both processes are terminated

REPRODUCIBILITY :
This bug can be reproduced always.
