Unable to Deploy Server Code

I am experiencing the following problem trying to deploy my custom server code using Deploy.bat (win environment). “Can not parse generic service: CodeRunnerException: CodeRunner did not return object on requestActionInvocation.” , but CodeRunner.bat works just fine.
If I try using the web console I dont receive any message.

I have sent an email to the support address with my jar (source are packaged inside) and some additional info, I attach here a screenshot of the error.

Hello, Federico,
We have assigned developer to investigate the issue. Ticket id is BKNDLSS-13236.

Hello, Federico.
I check your code and found, that you use static initialization of Logger object.
Please take look this documentation:
https://backendless.com/documentation/business-logic/java/bl_logging.htm

Pay attention to this line of code:

LogBuffer.getInstance().setLogReportingPolicy( 1, 0 ); 

Please, notify us about your progress.

Hi Oleg,
the problem is solved following your instructions, thank you very much.
