Eliminated printStackTrace() calls

Eliminated calls to printStackTrace() on Throwable as they go to stdout
and are not handled by logger.
Occurences has been replaced by calls to logger or modifications to
nearby logger calls (Throwable passed as last parameter).

Occurences in unit test classes left without modification.
