The ME8 SDK is not detected as J2ME platform, since it does not have preverify tool. Preverification is not supported on ME8 platform and hence will not be present in the SDK's bin directory anymore. The detection logic has to be enhanced to support this scenario. 

The following workaround allows the ME8 SDK to be recognized as a valid J2ME platform.
