Jazz Build Engine crashes if a Jenkins build engine is declared in my project area

I'm trying to set up a jenkins server to work together with my RTC.

In the same linux machine, I installed the JBE with the parametere "-engineId myBuildEngine", and everything starts correctly.

After that, I create my jenkins build engine in my project area called myBuildEngine, and then, the jbe demon crashes without explanation.

I executed jbe-daemon.sh in the terminal and I received this message:

[Jazz build engine] Exception occurred in build loop: CRRTC3540E: The following build engine is a Hudson/Jenkins build engine: "myBuildEngine". Only engines of type "Jazz Build Engine" can be used with the "-engineId" argument.
Without engineId jenkins cant execute any build related to RTC build engine.

My jbe and RTC server version is 5.0.1

This situation is strange because the first time I set up jbe, jenkins and RTC build engine declaration everything worked perfectly, but not after a reboot.
