> The documentation provided in NiFi does not include enough information on the
> default limitations of Java 7 that can offer result in Out of Memory: Permgen
> conditions. The Admin Guide should be updated in 2 places:
> 1. under system Requirements we should add a note about using Java 7 and
> point them to additional guidance under the bootstrap properties section.
> 2, In the bootstrap properties section we should document the commented out
> java 7 properties in the file and explain why they should have they should be
> used when running with Java 7.
> Further, the codecache issues present in Java 7 and Java 8 also warrant
> commentary as the results can be terrible and extremely hard to figure out.
