Well... It certainly doesn't look like J2ME has a bright future. Keeping it alive under present terms may be enough. The OpenJDK and Apache licenses protect against patent trolling by Oracle or IBM, so, that threat is not significant. The only problem would be the risk of deviating from current "safe" versions into Larry's patentland.
J2ME effectively died (became irrelevant) years ago. It still continues to ship in some low-end feature phones but no important developers are targeting new applications to that platform.
