using hibernate with mysql and option skip-networking

[vlad2005]

I want to use hibernate with mysql, using option skip-networking.
My hibernate.cfg is like this:

<hibernate-configuration>
 <session-factory>
 <property name="transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</property>
 <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
 <property name="hibernate.connection.password">xxxx</property>
 <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>
 <property name="hibernate.connection.username">xxxx</property>
 <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
 <property name="hibernate.cache.use_query_cache">true</property>
 <property name="hibernate.cache.use_second_level_cache">true</property>
 <property name="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</property>
 <property name="connection.shutdown">true</property>
 <property name="c3p0.min_size">5</property>
 <property name="c3p0.max_size">100</property>
 <property name="c3p0.timeout">100</property>
 <property name="c3p0.max_statements">50</property>
 <property name="c3p0.idle_test_period">30</property>
 <property name="show_sql">true</property>
 <property name="current_session_context_class">thread</property>
 </session-factory>
</hibernate-configuration>

At startup i receive this error:

09:32:18,169 WARN [ThreadPoolAsynchronousRunner] com.mchange.v2.async.ThreadPoolAsynchronousRunner$DeadlockDetector@67f6dc61 -- APPARENT DEADLOCK!!! Creating emergency threads for unassigned pending tasks!

If comment option skip-networking in my.cnf, everything work well.
How can be resolved?
