NoDd* classes

首先，使用真实的流程定义复现报告的 NoDb* 配置。阅读 DbSqlSession.java:202 中的 DbSqlSession.selectListWithRawParameter 和 ReflectUtil.java:140 中的 ReflectUtil.instantiate，然后将报告的两个异常追溯到其配置或流程定义输入。完成的标准是确认原因，并且 NoDb* 设置要么能够正常工作，要么报告具体且可采取行动的限制。

Hello,
did you tried use NoDb* classes to configure working project with real process defitions please?
Because I am getting exceptions below when I did.

java.lang.NullPointerException
	at org.flowable.common.engine.impl.db.DbSqlSession.selectListWithRawParameter(DbSqlSession.java:202) ~[flowable-engine-common-6.4.2.jar:6.4.2]

org.flowable.common.engine.api.FlowableException: couldn't instantiate class ${something}

	at org.flowable.common.engine.impl.util.ReflectUtil.instantiate(ReflectUtil.java:140)
	at org.flowable.engine.impl.bpmn.helper.AbstractClassDelegate.defaultInstantiateDelegate(AbstractClassDelegate.java:64)

Best Regards,
