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


Patch Set 5:

Many of these changes are essentially needed just for generating consistent 
tests results when we switch between different java versions. I wonder if this 
the right approach. We're essentially "forcing" the use of a data structure 
with different performance/memory tradeoffs than we had before. It may not have 
significant impact on performance/memory usage, but creates confusion. For 
example, I believe we may end up overusing linked* just to ensure results 
stability. Wouldn't it be better is we made the test results verification 
agnostic to order? Just some thoughts...
