RestService Not Working after applying WLS PATCH SET UPDATE 14.1.1.0.250108

We applied the Weblogic CPU patch (WLS PATCH SET UPDATE 14.1.1.0.250108) . after that our application Rest service request got stuck. Exactly the below code is blocking the request and we are receiving the stuck thread exception after the timeout.

BufferedReader in = new BufferedReader(new InputStreamReader(ContainerRequestContext.getEntityStream()));

Kindly let me know any Jar version is upgraded or any code change needs to be done.

Note: if we are reverting the CPU patch then we are not getting above issue. And its working fine.
