In the two Mac mavericks tested, java JDK was found in a different location. Furthermore, the JDK version numbers in the jdk installation folder need not be consistent. However, the means of finding out what javahome is, was consistent on Maverick. The java HINT that's set for search4j now goes through these steps to work out what the JAVAHOME hint out to be.
