Hey @joaohf! Looks like @mattyb149 has already started giving some input
but saw that there are a few test failures concerning expression language such
as the one below (full sample log is available at:
https://s3.amazonaws.com/archive.travis-ci.org/jobs/114414795/log.txt).
Haven't dug deep into the tests but wanted to call it out to your attention to
get a fix for later incorporation.
Thanks!

Time elapsed: 0.01 sec <<< FAILURE!
java.lang.AssertionError: java.lang.IllegalStateException: Attempting to
retrieve value of PropertyDescriptor[Index Operation] without first evaluating
Expressions, even though the PropertyDescriptor indicates that the Expression
Language is Supported. If you realize that this is the case and do not want
this error to occur, it can be disabled by calling
TestRunner.setValidateExpressionUsage(false)
