Corrupted database

I am sorry to say that, but it looks like a corruption problem. I am very interested in analyzing and solving this problem. Corruption problems have top priority for me. I have a few question:

- Could you send the full stack trace of the exception including message text?
- What is your database URL?
- You can find out if the database is corrupted when running SCRIPT TO 'test.sql'
- What version H2 are you using?
- With which version of H2 was this database created? You can find it out using: 
  select * from information_schema.settings where name='info.BUILD_ID'
- Did you use multiple connections?
- The first workarounds is: append ;RECOVER=1 to the database URL. 
  Does it work when you do this?
- The second workarounds is: delete the index.db file 
  (it is re-created automatically) and try again. Does it work when you do this?
- The third workarounds is: use the tool org.h2.tools.Recover to create 
  the SQL script file, and then re-create the database using this script. 
  Does it work when you do this?
- Do you use any settings or special features (for example, the setting LOG=0, 
  or two phase commit, linked tables, cache settings)?
- Is the application multi-threaded?
- On what operating system, file system, and virtual machine (java -version)?
- How big is the database?
- Is the database usually closed normally, or is process terminated forcefully 
  or the computer switched off?
- Is it possible to reproduce this problem using a fresh database 
  (sometimes, or always)?
- Are there any other exceptions (maybe in the .trace.db file)? 
  Could you send them to me please?
- Do you still have any .trace.db files, and if yes could you send them?
- Could you send me the .data.db file where this exception occurs?
