      Description

      If the user starting the Tika Server does not have the path to java configured in its PATH var, the following error appears in the logs :

      java.io.IOException: Cannot run program "java": error=2, No such file or directory

      By checking the TikaServerWatchDog class I noticed that the startProcess method of the ChildProcess private class is using the 'java' argument. As my user only have the JAVA_HOME configured in its /etc/profile and not the path to java, this explains the error.

      It would be better if the startProcess relies on the JAVA_HOME env var to use java instead of assuming that the java program is configured in the PATH env var of the user.
