I upgraded to the latest patch release. It seems a bit less painful than before. One problem is that the sqldevloper.conf file was overwritten so I lost this setting:
#Alternative to KeepResident
AddVMOption -Dsun.awt.keepWorkingSetOnMinimize=true
I guess there's no easy way of handling this but it would be nice if something in the release notes reminded us to take a backup of such files.
Cheers, APC
