[jira] [Assigned] (BIGTOP-843) It would be really cool if
bigtop-detect-javahome were smarter and didn't pick a 32-bit JVM, or a 1.7
JVM set with default

> I see more and more folks with whacked versions of java configured in /usr/java/default or /usr/lib/jvm/default-java that are pointing to 32-bit JVMs or are simply not even a 1.6 JVM. I was wondering if we could do a bit more intelligence in this script and run a java -version to rule out a 32-bit JVM or a 1.7 JDK? Or would that be too error prone?
