Cannot call undefined in jvm-npm.js

With milestone6 I get the following error:

javax.script.ScriptException: TypeError: Cannot call undefined in src/main/resources/vertx-js/util/jvm-npm.js at line number 121

The problem points to the following line

var synchronizedDoRequire = Java.synchronized(doRequire, verticleFactoryClass);

In milestone5 everything worked correctly.

This also happens if I just run mvn test so it seems it's not my code causing this issue. I use JDK 1.8.0_31 by the way. Maybe there's some Nashorn feature that has been added in 1.8.0_40?

Thanks,
Michel

[vietj]

yes please try the latest JDK 1.8.0_45, that should fix the problem.

[michel-kraemer]

OK. Done. I can confirm it's working with 1.8.0_45. Thanks a lot!

I'm closing this one, but I wonder if it might be worthwhile supporting older versions as well or at least issue a warning or a sensible error message.

Cheers,
Michel
