Make sure the following files on executing JRE is NOT corrupted/modified/deleted.

• jre\lib\security\local_policy.jar
• jre\lib\security\US_export_policy.jar

I had a similar issue which was caused by manually copying these two files from different java version. Resolved after replacing with original files.
