NoSuchMethodError при выполнении HQL и C3P0 включен

Question

Hibernate отлично подходит для меня, пока я не попытаюсь включить C3P0, после чего я столкнулся с проблемами. Я добавил это в моем pom.xml:

<dependency> 
     <groupId>org.hibernate</groupId> 
     <artifactId>hibernate-c3p0</artifactId> 
     <version>5.0.7.Final</version> 
    </dependency> 
    <dependency> 
     <groupId>com.mchange</groupId> 
     <artifactId>c3p0</artifactId> 
     <version>0.9.5.2</version> 
    </dependency> 

И это на мой hibernate.cfg.xml:

<property name="hibernate.c3p0.max_statements">0</property> 
<property name="hibernate.c3p0.timeout">100</property> 
<property name="hibernate.c3p0.idle_test_period">100</property> 
<property name="hibernate.c3p0.min_size">10</property> 
<property name="hibernate.connection.provider_class">org.hibernate.service.jdbc.connections.internal.C3P0ConnectionProvider</property> 
<property name="hibernate.c3p0.acquire_increment">1</property> 
<property name="hibernate.c3p0.max_size">100</property> 

Когда я делаю это, и попытаться выполнить некоторые HQL используя инструменты Hibernate от JBoss, я получаю следующее исключение:

код работает корректно во время выполнения, и, кажется, уважая мои настройки C3P0.

Answer 1

c3p0 0.9.2.x является старым и не поддерживает методы JDBC4.

Обновите текущую версию c3p0-0.9.5.2.
