xa事务at io.seata.rm.datasource.xa.ConnectionProxyXA.checkTimeout(ConnectionProxyXA.java:295) "this.timeout" is null

[langhan]

• I have searched the issues of this repository and believe that this is not a duplicate.

Ⅰ. Issue Description

debug时看ConnectionProxyXA new 以后调用了init时是有值的，不知道是不是被cleanXABranchContext清除了，再复用时就没有了

Ⅱ. Describe what happened

If there is an exception, please attach the exception trace:

为什么会直接复用connectionProxy的连接？你的连接池如何创建的？理论上应该是datasourceproxyxa代理连接池datasource，从连接池里拿到连接进行init，如果把connectionproxy进行复用就会出现cleanXABranchContext，值为null，并且没有进行init的情况，导致timeout为null

[funky-eyes]

问题应该是使用其executeBatch时未开启本地事务，导致sqlsession使用的connection被复用，而如果对connectionproxyxa进行commit会清空初始化的属性导致了这个问题，我们后续修复一下
