hi , I am using java 1.6 SDK, node 10.3.3.
npm install java works well.
Then I tried to run the packaged tests, There are two packaged test folders -- test and test8
Test8 contains lambda, so it will fail in my environment as I have SDK 1.6.
I modify the package.json to invoke the test folder. (instead of test8 folder).

Then I try the npm test, this fails with the following assertions:
