I'm trying to run some j2me nokia games with "Rum MIDP Application" of the SUN J2ME Wireless Toolkit 2.0 Beta 1 suite but i obtain the following error:

ALERT: Native method 'com/nokia/phone/sdk/concept/util/io/bridge/Bridge::reserveBridge0' not found

Someone knows why and what i can do to avoid the problem?
Thank you in advance!!!
