It is related, but is different.
ISPN-1649 is on 'dropTablesOnExit". This one is on failures in creating tables when using H2 mem configuration.
Hmmmm, we use createTableOnStart=true in our testsuite with in-memory H2 database without problems:
In spite of the message showing an exception, the message is a DEBUG message, so maybe this can be expected by H2/C3P0 ? What matters is whether the app then works as expected or not.
I rerun my tests with latest ISPN code, I do not see this problem anymore. I'll mark this as "Answered".
Thanks for taking time to look into this.
