Hello,
we are currently using H2 on Android for accessing from multiple processes.
In order to allow backups and recovery of the database in case of
corruption we wrote a simple app to use the recovery-tool to backup the
database.
Currently we have a database with a size of only 1.9MB, but can not dump
the database using the recovery-tool.
We can although dump the database with empty tables.
The problem is this exception:
java.lang.IllegalStateException: Unsupported type 17 [1.4.191/3]
