> 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}
>  
> Sample appender in log4j2.xml
