Hi Sudharma, UUF will turning into the debug mode from "-Xdebug" JVM parameter(when remote debugging is on).
When UUF debug mode is on, It doesn't cache anything. Trying to reload the application per each request. This error occurs when trying to reload the app. This is a known bug and fixed with [1]. Also it deactivates the debug pointers after starting the debug mode Can you verify this behaviour? This should not affect your IDE or break pointers.
