SQLWarnings in Profiler

[William Lindsay]

I'm running FlightRecorder and it is reporting a large amount of SQLWarnings being generated.  I set IgnoreWarnings on the jdbcTemplate, but the number still shows high.  There is a NULL message in the warning.  I would like to either understand the issue and resolve, or suppress these SQLWarnings,  as it appears there is load on the application.

Hello!

H2 database doesn't support warnings and cannot produce java.sql.SQLWarning, if you see them, they came from some other software.
