 Work around :

1.     Navigate to below location(on both windows and linux) :

            <User_Home>/.jdeveloper/system12.2.1.0.42.151011.0031/

            Eg For windows - C:\Users\<USER>\AppData\Roaming\JDeveloper\system12.2.1.0.42.151011.0031\system_cache

2.     Delete  the "system_cache" directory or rename the "system_cache" directory.

3.     Start the Jdevloper and it comes up!!!!
