1. add a space between **}** and **finally**
2. why we need to move some codes about closing **ServerSocket** in **catch** code block to **finally** code block? this will
make codes in **Line677-Line685** redundant
3. If **numRetries** don't count **SocketTimeoutExceptions**.is this code facing an endless loop if SocketTimeoutExceptions always happen for a long time? this way of handling SocketTimeoutException is appropriate?

1. i had removed **finally** code block in my newest code.
2. according to jira , the **SocketTimeoutException** was likely thrown every about 49days, maybe unsigned int -1. Or, we can follow [Karaf](https://issues.apache.org/jira/browse/KARAF-3325l) to fix this code. but i think it was thrown too often.
