这个报错什么原因 success false message 启动流程失败! detailMsg show true code 500 data javalangNullPointerExceptionrntat javautilObjectsrequireNonNullObjectsjava203rntat comgithubbenmanescaffeinecacheBoundedL

这个报错是由于空指针异常引起的。具体的调用栈信息如下：

java.lang.NullPointerException at java.util.Objects.requireNonNull(Objects.java:203) at com.github.benmanes.caffeine.cache.BoundedLocalCache.put(BoundedLocalCache.java:1980) at com.github.benmanes.caffeine.cache.BoundedLocalCache.put(BoundedLocalCache.java:1955) at com.github.benmanes.caffeine.cache.LocalManualCache.put(LocalManualCache.java:130) at net.oschina.j2cache.caffeine.CaffeineCache.put(CaffeineCache.java:62) at net.oschina.j2cache.CacheChannel.set(CacheChannel.java:268) at net.oschina.j2cache.CacheChannel.set(CacheChannel.java:248) at com.redxun.cache.impl.J2CacheImpl.set(J2CacheImpl.java:18) at com.redxun.cache.CacheUtil.set(CacheUtil.java:23) at com.redxun.bpm.activiti.ext.FlowDefCache.add(FlowDefCache.java:48) at org.activiti.engine.impl.bpmn.deployer.CachingAndArtifactsManager.updateCachingAndArtifacts(CachingAndArtifactsManager.java:55) at org.activiti.engine.impl.bpmn.deployer.BpmnDeployer.deploy(BpmnDeployer.java:93) at org.activiti.engine.impl.persistence.deploy.DeploymentManager.deploy(DeploymentManager.java:58) at org.activiti.engine.impl.persistence.deploy.DeploymentManager.resolveProcessDefinition(DeploymentManager.java:123) at org.activiti.engine.impl.persistence.deploy.DeploymentManager.findDeployedProcessDefinitionById(DeploymentManager.java:76) at...

根据调用栈信息可以看出，报错发生在 com.redxun.bpm.activiti.ext.FlowDefCache.add(FlowDefCache.java:48) 这个方法中。具体的异常信息是 java.lang.NullPointerException，但是没有提供详细的错误信息（detailMsg为空）。

根据调用栈信息来看，可能是在向缓存中添加数据时出现了空指针异常。具体原因需要查看代码中的相关逻辑来进行进一步分析和排查
