@spmallette Off the top of my head:
1. Maybe security through obfuscation? But this is a open source library
and one can easily know which method does what based on matching the version of
the library with the type signatures
2. This will make class files a little larger since before Java8 only the
method signature was stored. Also this does appear to only be supported by
Java8, which is fine since Tinkerpop requires it:
https://docs.oracle.com/javase/8/docs/technotes/tools/windows/javac.html.
Note, not there for Java7.
I do see some mention of the larger memory footprint issue here:
http://docs.oracle.com/javase/tutorial/reflect/member/methodparameterreflection.html.
So that is a consideration. In this case, with gremlin-core the difference
seems to be about 1K when looking at the uncompressed class file size
difference.
