Hi Hendrik,
Thanks a lot for replying..
Here is a case,
I call one method from one of the working thread, and i want it to
return true if successful otherwise false.

pls advice

Agreed, returning out of a catch block will in most cases be something
to be avoided.
(Most best practices recommend striving for a single return)

It can lead to hard to read code when a finally block is added. The
code in the finally will execute before the return even though it is
located after the return in the source.
try{
  // do risky stuff
}catch( Exception e){
 return false;
} finally {
 // clean up resources
}

I do agree with your other post that instead of trapping the exception
and returning a boolean that he should just let the exception
propogate. Swallowing the exception can lead to hard to debug code.
