Description

JDBC states that "isReadOnly(int column) Indicates whether the designated column is definitely not writable."
Note that it does NOT say that the resultset is not writable.
So isReadOnly() should return false if it is applied to a ResultSet which was obtained by querying a table, which it doesn't. It always returns true.

I will attach a testcase for the described behaviour.
