[Hsqldb-developers] Problems with 2.0 RC8

Hello Devs!

at first I really like the speed of the  2.0 HSQLDB... though I ran
into one issue:
Often when I not close the HSQLDB properly   it fails to restart on
the files again .. and I get the following error messages from java:
(I never had such a problem with 1.8.x releases)
is this a bug or do I have to threat 2.0 differently as 1.8 ?
