Error Signing JavaFX jar

I'm getting this errors trying to sign a Java FX app with a custom certificate (crt) that works fine if I use it directly with jarsigner

...

Java FX Packager: JavaFX sign task has failed for: /Users/Sebastian/Library/Caches/IntelliJIdea12/compile-server/_temp_/artifact2064713574984050972unzipped/deploy/IntegraAgentFXDataCapture.jar.

...

Compilation completed with 6 errors and 0 warnings in 5 sec

any idea??
