intercept all java JVM calls

Good man David wrote a script to log all the calls to Java with the parameters passed:
mv /usr/lib/jvm/jre-1.7.0-oracle.x86_64/bin/java /usr/lib/jvm/jre-1.7.0-oracle.x86_64/bin/java_
vi /usr/lib/jvm/jre-1.7.0-oracle.x86_64/bin/java

#! /bin/bash

LOG_DIR=/tmp/log_puppet_weblogic
LOG_FILE=$LOG_DIR/log.txt
echo "+++++++++++++++++++++++++++++"  | tee -a $LOG_FILE
echo "+++ EXECUTING JAVA. CMD: java""$@"  | tee -a $LOG_FILE

java=$(readlink -f $0)
echo "+++ EXECUTING JAVA. time: "`date +"%Y%m%d-%H%M%S"` | tee -a $LOG_FILE
echo "+++ EXECUTING JAVA. java: $java"  | tee -a $LOG_FILE
echo "+++ EXECUTING JAVA. cp: $CLASSPATH"  | tee -a $LOG_FILE

for arg; do
#  if [[ ${arg: -3} == ".py" ]] || [[ ${arg: -4} == ".xml" ]]; then
  if [[ ${arg: -3} == ".py" ]]; then
    echo "+++ EXECUTING JAVA. cat $arg. START."  | tee -a $LOG_FILE
    cat $arg  | tee -a $LOG_FILE
    echo "+++ EXECUTING JAVA. cat $arg. END."  | tee -a $LOG_FILE
    f=file-$(basename $arg)-$(date +"%Y%m%d-%H%M%S")
    cp $arg $LOG_DIR/$f
  fi
done

f=$LOG_DIR/log-$(date +"%Y%m%d-%H%M%S").txt
echo "+++ EXECUTING JAVA. running. log: $f"  | tee -a $LOG_FILE
original_java=${java}_
set -e
(($original_java "$@") 2>&1 ) | tee $f

EXIT_CODE=${PIPESTATUS[0]}

echo "+++ EXECUTING JAVA. cat $f. START."  | tee -a $LOG_FILE
cat $f | tee -a $LOG_FILE
echo "+++ EXECUTING JAVA. cat $f. END."  | tee -a $LOG_FILE

echo "+++ EXECUTING JAVA. exit code: $EXIT_CODE" | tee -a $LOG_FILE
echo "+++ EXECUTING JAVA. END."  | tee -a $LOG_FILE

exit $EXIT_CODE

chmod 775 /usr/lib/jvm/jre-1.7.0-oracle.x86_64/bin/java
At this point, all calls will be logged to /tmp/log_puppet_weblogic/log.txt and the stdout of each command will go into a separate file in /tmp/log_puppet_weblogic/ folder. This is particularly useful to trace all the WLST calls.
