DBAppender swallow NullPointerException
---------------------------------------

                 Key: LBCORE-189
                 URL: http://jira.qos.ch/browse/LBCORE-189
             Project: logback-core
          Issue Type: Bug
          Components: Appender
    Affects Versions: 0.9.26
            Reporter: Artyom Kalita
            Assignee: Logback dev list
            Priority: Minor


logback.xml :

<appender name="DB" class="ch.qos.logback.classic.db.DBAppender">
    <connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource">
    <dataSource class ="com.mchange.v2.c3p0.ComboPooledDataSource"></dataSource>
        <driverClass>com.mysql.jdbc.Driver</driverClass>
        <url>jdbc:mysql://localhost:3306/mrb</url>
        <user>root</user>
        <password>admin</password>
    </connectionSource>
</appender>

Java code (using DBAppender):

Date dateFrom = null;
log.info("Processing code {}; code type is {}; request date {}; record from date {}",new Object[] { code, codeType, new Date(), dateFrom });

DBAppender  had null pointer exception on 141 line because of dateFrom, but this exception is swallowed and not shown.
