Gary D. Gregory commented on LOG4J2-2667:
-----------------------------------------
If you are getting the same exception out of the JDBC driver, then this still
looks to me like a bug in that JDBC driver. If I were you I'd create the
simplest JDBC test only using the JDBC driver and submit it as a bug to SQLite.
> "Values not bound to statement" when using JDBC appender, appender does not
> respect bufferSize="0".

> Project: Log4j 2
> Issue Type: Bug
> Components: Appenders, Core

> Environment: Oracle Java 11.0.3, Windows Server 2016, Spring Boot
> 2.1.6

> Since version 2.11.2, the log4j2 library was unable to log message on
> database via JDBC connection. When using 2.11.1, no such problem was found.
> root cause:
> In org.sqlite.core.CorePreparedStatement, below function was called, but
> paramValid local variable is not initialized. Value of
> "paramValid.cardinality()" is always 0 which does not match with the total
> number of parameter.
>
> {code:java}
> protected void checkParameters() throws SQLException
> {
> if (paramValid.cardinality() != paramCount)
> throw new SQLException("Values not bound to statement");
> }
> {code}
