Hi Sean, I can not get them to run. 

My steps are: 
{noformat}
build/sbt -Pjava8-tests
project java8-tests
test

Or just run

build/sbt -Pjava8-tests java8-tests/test:test
{noformat}

P.S I can not run the build from maven somehow, I can get compiler to crash consistently at
graphx.

> Having tests that validate the same code compatible with java 8 and java 7 is like asserting
that java 8 is backward compatible with java 7 and still supports java 8 features(lambda expressions
to be precise). This was once necessary as asm was not compatible with java 8 and so on. 
> Running java8-tests on the current code base results in more than 100 compilation errors,
it felt as if they are never run. This is based on the fact that compilation errors have existed
for a pretty long period. So IMHO, we should really remove them, if we don't plan to maintain.
> Thoughts?
