One way to check this would be to launch the JVM using a script that
captures the exit code of the process:
$!/bin/sh
# Grab all these variable definitions from bin/catalina.sh
"$_RUNJAVA" "$LOGGING_CONFIG" $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
-Dcatalina.base="$CATALINA_BASE" \
-Dcatalina.home="$CATALINA_HOME" \
-Djava.io.tmpdir="$CATALINA_TMPDIR" \
org.apache.catalina.startup.Bootstrap "$@" start \
>> "$CATALINA_BASE"/logs/catalina.out 2>&1
result=$?
echo "JVM existed with status code=${result}"
If it's 0, then the changes that this is due to a System.exit(0) call
are very high.
You could also try running under a SecurityManager, and prohibit
System.exit() calls.
