There seems to be a test failing in the es5-multimodule-test profile. I kicked off Travis a couple of times to see if it was some kind of timing problem but it appears to be consistent.

Well that stinks. If I run all the es5-multimodule-test tests locally I get a failure right here https://github.com/visallo/vertexium/blob/master/test/src/main/java/org/vertexium/test/GraphTestBase.java#L3112 but when I run testGraphQueryHasAuthorizationWithHidden by itself I get a pass. If I run testGraphQueryHasAuthorization and testGraphQueryHasAuthorizationWithHidden together I can get a failure. But if I set breakpoints I get a pass.

@mwizeman should be fixed now. Just waiting for CI
