To submit a bug, you'll need to open a Service Request with My Oracle Support.
However, this sounded pretty bad, so I tried it.
Fortunately, or unfortunately dependending on your point of view, it works just fine for me.
What I did.
- Running instance of 4.0.2 using JDK8 - technically not supported BTW
- Preferences, switch to Windows LNF
- Confirm that will require a restart
- SQLDev shuts down
- SQLDev starts up
- Splash screen visible
- SQLDev UI visible
Repeated steps to switch back the other way, works as expected.
As far as LNFs go, the Windows one isn't that appealing. We are looking at adding support for other LNFs in the future, if you're curious.
>SQL Developer 1.5.5
Yeah, can you upgrade? You're using a very old, and very unsupported version of SQL Developer.
