Sometimes when opening a new tab in SQL commander, a NullPointerException occurs. To reproduce, just keep hitting Ctrl+T unitl the error window pops up. Usually happens within 2-3 tries. The same error happens when starting DBVisualizer (every time, as far as I can tell).
An internal error occurred:
The error may have affected the application state.
Please notify vendor.

Seems as if there are some major flaws in the latest 1.6.0_19 and now also 1.6.0_20 versions of Java on Windows. Other users have reported similar problems and downgrading to 1.6.0_18 (or older) seem to solve it.
Try this and keep us updated.
We will most likely add a notification of this situation on our web shortly as I believe there are many users experiencing this.

Re: Opening a new tab causes NullPointerException
I reverted to 1.6.0_18, and everything seems OK now. Thanks.
Hopefully, the guys at Oracle \[sic\] will fix this soon. :)
