Unable to start gwt hosterd mode client

[Luca Farsetti]

Hello all, in my fresh new mavericks 10.9.3 i'm not able to start gwt client anymore.
I'm able to compile with

compile-gwt-modules

but when i execute 

run-gwt-client

the command terminate without errors, but gwt hosted mode client doesn't start.

The plugin is installed in a firefox 25 version

My project use grails 2.2.4, gwt 2.4 and gwt plugin 0.7.1 and java 1.7.0_60 64bit. 

I checkouted it on another machine with ubuntu 13.10, java 1.7.0_55 64bit and everythings seems fine

Any ideas?

Thanks in advice

Luca
