Hi Rasika, I think your requirement is to attempt reconnection when some external connectivity is lost.
In this case I think it is better to handle this with your own thread, which is quite similar to the code you have posted initially. The thread can be created and kept in your connector level (say connection recovery thread). You can make it null once reconnection completed and release any resources, so that the thread can be GC ed properly. I think managing dedicated thread is better as it needs to be done at a very low level. Thread pool is more suited to handle 1. common, extensible, pluggable, business workers 2. I/O read and write but it is not good to use thread pool to handle connection management logic, because of timing and pool starvation. Also it will give you less coupling, good modularity and testability. WDYT?
