ASSERT FAILED RowChanger already open

[Rami Ojares / PDF-Comics Oy <ra...@absinth.fi>]

Has anybody any ideas what this exception could mean.

It comes when I am inserting rows in a table using a PreparedStatement.
Every once in a while I rollback a statement or two and continue inserting.

Here is the trace from server side:

Oh, and there is a security exception again.
I am not even allowed to see exceptions because of Derby's paranoia ;-)
Please let me use my software on my own computer!
