hidden directories under /etc/

[Omair Majid]

Hi,

I recently discovered that openjdk creates hidden directories under 
/etc/ [1]. I would like to propose that those directories should be made 
explicit.

webrev at:
http://cr.openjdk.java.net/~omajid/webrevs/hidden-dirs-under-etc/01/

The patch modifies the directory names to make them visible by default. 
The directory /etc/java/ already exists on many linux distributions - 
jpackage uses it - so it seems like a useful replacement directory.

The patch also renames systemPrefs to system-prefs to make it slightly 
more consistent with existing directories under /etc/.

Does anyone have any thoughts or concerns?

Thanks,
Omair
