Unable to run BrowserSim. Icon and command to run BrowserSim is available but once invoked nothing happened.

The same behavior is on Mac Os + JBDS and Linux 64bit + JBT.

There is no error in error.log.

There are these errors in console:

Exception in thread "main" java.lang.SecurityException: class "org.eclipse.swt.browser.BrowserInitializer"'s signer information does not match signer information of other classes in the same package
