Xavier Coulon resolved JBIDE-17877.
-----------------------------------
    Resolution: Won't Fix


[~dgolovin],

thanks for the reply. There is no exception at the JAX-RS tooling level when processing the code sample, and there's an endpoint for the Java method in the Project explorer, as expected. 

So, I'm closing this issue.
