There is an open issue about shutdown defrag corrupting db,
https://github.com/h2database/h2database/issues/187 . I've had similar
issue with non-split 1.4.190 DB. In my case the issue was, when opening DB
that was shut down with shutdown defrag,
Caused by: java.lang.ClassCastException: org.h2.value.ValueLong cannot be cast
to java.lang.Long
at org.h2.store.LobStorageMap.init(LobStorageMap.java:128)
at org.h2.engine.Database.open(Database.java:767)
at org.h2.engine.Database.openDatabase(Database.java:269)
Sorry, I couldn't come up with a nice isolated test case (yet). It happens
in rather complex testing scenario where the DB gets re-opened very soon -
possibly concurrently with an ongoing shutdown defrag, but H2 locks should
take care of that, right?
Best Regards,
Joonas
