Usable output from java on z/OS generally, but especially z/OSMF

The output from java on z/OS is almost unusable. A case in point is z/OSMF. This is now promoted as a strategic part of z/OS and now seems to be a required task, automatically started at IPL. The current output has no timestamps, rendering it of limited use in systems with lots of output. It is difficult to tie an error message on the log to a recent z/OSMF activity. Furthermore, the messages are incomprehensible for someone without a vast knowledge of java classes or a stack of documents to refer to. The output from java needs to a) Be timestamped, and b) be more relevant to a 'norma' user.
