Lily Wei updated DERBY-4441:
----------------------------

    Attachment: DERBY-4441-4.diff.txt

Thanks, Knut.
I include the new patch for this bug.
The changes include:
1. Move places further left for printPropertyIfNotNull()
2. add @param tags or two getJavProperty methods. Don't want to have java warning. 
3.Add the comment to explain nullUnavailable parameter for the two-argument getJavaProperty()
method.

I run tests for Suits.all and derbyall. They passed with sun jvm on Windows 7 env.
I did not run test against ibm jvm. The patch is ready if we don't have any diff against ibm
jvm.

> It would be nice if sysinfo printed out more specific jvm information that is provided
with java -version. At least with the IBM jvm the system  properties java.runtime.version
and java.fullversion give some more (but not all) information.   More research is needed across
multiple jvms to tie it down.  Alternatively sysinfo could dump *all* the system property
information, but that could make the output pretty big and show irrelavant information in
some contexts.
