NPE в c3p0 NewProxyConnection.prepareStatement для кварца

0 голосов
/ 21 марта 2019

Теперь использую кварц 2.3.0 с hibernate-c3p0 5.4.1.Final, но получаю исключение ниже (см. Подробности трассировки стека ниже). Все работало нормально, внезапно начал получать это.

Использование, org.springframework.scheduling.quartz.SchedulerFactoryBean и org.springframework.scheduling.quartz.SpringBeanJobFactory вместе с конфигурацией источника данных ниже 

<bean id="dataSource"
        class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="com.mysql.jdbc.Driver" />
        <property name="jdbcUrl" value="#{'jdbc:mysql://' + systemEnvVarLoader.getSysEnvConfigProps('RDS_ENDPOINT') + ':' + systemEnvVarLoader.getSysEnvConfigProps('RDS_PORT') + '/' + systemEnvVarLoader.getSysEnvConfigProps('RDS_SCHEMA')}" />
        <property name="user" value="#{systemEnvVarLoader.getSysEnvConfigProps('RDS_USERNAME')}" />
        <property name="password" value="#{systemEnvVarLoader.getSysEnvConfigProps('RDS_PASSWORD')}" />
        <property name="minPoolSize" value="5" />
        <property name="maxPoolSize" value="20" />
        <property name="maxIdleTime" value="600" />
        <property name="maxStatements" value="50" />
        <property name="testConnectionOnCheckout" value="true" />
    </bean>

Трассировка стека, как показано ниже:
