=====

One strange behavior that i identified is when i compile everything it hangs, 
but after hanging if i just compile one module again it launches.

After launching it request me if i wish to install nb-javac into my platform 
application.

 

=====

Im trying to understand if the problem is related to JDK 11.0.2 or the Netbeans 
imcompatibility with JDK 11 for platform applications.
