Instead of simply doing; "java ..." we do "exec java ...". Why have we used
exec here? I'm trying to solve the restart issue using exit codes, and when
exec is used, the process exit code cannot be captured.

Its good to use exec so that the parent shell process doesn't hang around.
That's common practice for shell scripts which set up a bunch of stuff and
run something else right at the end.
But that should not be a problem as the process exit status should be that

worked!
Earlier the script only had "exec java ..."

No saying "sh -c .." means you're creating a new shell and then exec'ng in
there. In that case you might as well just say "java .." (without the exec
at all).
Doesn't having "exec java" at the end give the return code of the java
command to the calling shell? That's what's spsed to happen.

If you do;
$ exec ./foo.sh
You will simply see the following line;
[Process completed]
and the control does not return to the current shell.

This is what I'm doing in the wso2server.sh. When I restart, I issue a
System.exit(121) command. So the shel will spawn a new Java process once the
current one exits. This can be done on Windows too with the ERRORLEVEL
variable. So, we are relying on the original process which spawned the java
proc
This solution is working on Windows as well! Here is the relevant change to
the wso2server.bat
:runJava
"%JAVA_HOME%\bin\java" -Xbootclasspath/a:%CARBON_XBOOTCLASSPATH% -Xms256m
-Xmx512m -XX:MaxPermSize=128m -Dimpl.prefix=Carbon
-Dcom.sun.management.jmxremote -classpath %CARBON_CLASSPATH% %JAVA_OP
Ah ok now I understood what you want to do .. yep sounds good.
Only change you could do is instead of saying "sh -c 'exec java ...'" you
could simply say "java ...". Essentially you're creating a shell and
immediately running one command so might as well run that command directly.

This solution works well on Ubuntu 10.10 as well.

I have tested this on Mac OS x 10.6, Ubuntu 10.10 as well as Windows 7
Ultimate. The solution works perfectly on all of this platforms and hence I
have committed the code. Now we can review and resolve all issues related to
memory leaks on restart.

Great. I tried this on Ubuntu 10.04 a few minutes ago, and it works
perfectly. Verified doing 'ps -ef', and performing multiple sequential
restarts as well.
Thanks,
Senaka.
