Error while executing code in user defined java class in PS ver 5.5 T3 instance-- Non-abstract class "Processor" must implement method "public abstract boolean

Issue: Found that in PS ver 5.5 of T3 instance 'while loop with true condition' is giving error at the time of compilation.
e.g.
         while(true){
                 //code
          }
2. System.exit(0) also not working.

Solution:  The while loop has restrictions. Please refer to the release note & below point.

The while(true) and for ;; are restricted java constructs in user-defined java class.
They are not allowed. There was an issue regarding this in the 5.1.1 release. We suggest you can use the start loop & stop loop instance of while loop.
