> If JAVA_HOME is not set, bigtop-detect-javahome has a very quirky search
> order that can have surprising behavior.
> Some problems:
> - because the "defaults" (like /usr/java/default,
> /usr/lib/jvm/default-java, /Library/Java/Home) are in the middle of the
> search list, bigtop will pick up other random JDKs instead of the 'default'
> the user already has set up on the system.
> - due to use of wildcards, earlier minor versions can be preferred over
> later minor versions, e.g. /usr/java/jdk1.6* will find 1.6.0_31 before
> 1.6.0_43, which is probably not what the user wants.
> - 1.6 and 1.7 preference order is not consistent (e.g. generally 1.6 is
> preferred over 1.7 but not for openJDK)
> This is related to previous issue:
> https://issues.apache.org/jira/browse/BIGTOP-843
