Wow!!
So, how can I find the problem? I can’t find any useful information from this log..
For this reason I had to remove portion of code from my mxml and from all the imported packages.. 2 hours of “debugging” gave me the solution!

A syntax error in a declaration of an XMLList was the problem!  Fixed the line also the compiler started to run again with no problems.
