Handle java exceptions

While srm starts the transfer some errors may occur, e.g. site is timed out. I need to handle this somehow and try another site. Here is an example of recent error from FM logs when FNAL has been cut off:

{{{
SRMClientV2 : srmPrepareToGet: try # 1 failed with error
SRMClientV2 : ; nested exception is:
