Change subject: IMPALA-3643/IMPALA-5344: Fix FE tests on Java 8

Patch Set 6:

Lars can obviously chime in but I'll give my rationale for the +1.

My understanding is we will stay at Java language compatibility level 7 but remove the dependency
of Impala tests on implementation-defined behaviour of Sun JDK 7. I think we should consider
that dependence on implementation-defined behaviour a bug. There are no guarantees about iteration
order in the Java spec and it could change at any point, e.g. in a JDK update or even between
different instances of HashMaps.

OpenJDK 7 is near EOL and Sun JDK 7 is EOL so if we don't fix this we'll soon be in a situation
where our tests only pass on obsolete JDKs.

This inconveniences me personally since I'm using OpenJDK 8 and in general it's unreasonable
to expect contributors to develop on obsolete JDKs.
