Tomcat: Persistência de sessão não funciona com o MySQL

Question

Estou trabalhando na adição de persistência de sessão no Tomcat com o MySQL, mas infelizmente isso não está funcionando. Nada no banco de dados. Eu estou tentando salvar informações de sessão para que os usuários estejam conectados mesmo após o reinício do tomcat. Esta é a configuração que tenho:

tabela:

create database tomcat;

create table tomcat$sessions
(
    id varchar(100) not null primary key,
    valid char(1) not null,
    maxinactive int not null,
    lastaccess bigint,
    data mediumblob
);

context.xml:

<Manager className="org.apache.catalina.session.PersistentManager" debug="3" saveOnRestart="true" maxActiveSessions="-1" 
minIdleSwap="-1" maxIdleSwap="-1" maxIdleBackup="-1">
<Store className="org.apache.catalina.session.JDBCStore"
driverName="org.gjt.mm.mysql.Driver"
connectionURL="jdbc:mysql://localhost/tomcat?user=USERNAME&amp;password=PASSWORD&amp;useSSL=false"
sessionTable="tomcat$sessions"
sessionIdCol="id"
sessionDataCol="data"
sessionValidCol="valid"
sessionMaxInactiveCol="maxinactive"
sessionLastAccessedCol="lastaccess"
checkInterval="60"
debug="99" />
</Manager>

logging.properties:

# To see debug messages in TldLocationsCache, uncomment the following line:
#org.apache.jasper.compiler.TldLocationsCache.level = FINE
org.apache.catalina.session.PersistentManager.level = ALL
org.apache.catalina.session.PersistentManager.useParentHandlers = true
org.apache.catalina.session.level = ALL
org.apache.catalina.session.useParentHandlers = true
