Kathey Marsden commented on DERBY-1272:
---------------------------------------

I have been thinking about this issue, perhaps the full sysinfo is just 
overkill for derby.log, especially considering all the extra permissions that 
are required. The critical information that is routinely needed in derby.log 
that is not there already is the jvm version and if possible the derby.jar 
location (not sure how to do this).  Maybe we should try to print just this 
information compactly to derby.log and not go for the full sysinfo.




> Change sysinfo to print to error log (derby.log) on boot of derby  if 
> derby.stream.error.logSeverityLevel=0

> It is often very difficult to collect correct sysinfo output from user 
> environments because  sysinfo run from the commandline does not have the same 
> classpath as the jvm that started Derby or Derby was loaded with a custom 
> classloader.
> It would be very helpful in assisting users in diagnosing their issues if 
> sysinfo dumped to the error log if  derby.stream.error.logSeverityLevel=0  or 
> even by default.
