datax 采集源头跟目标connection sleep资源不释放

1.采集300多张表，目标库与源头库connection一有关闭，很多sleep连接导致数据库挂死。
2.新版本有无有解决这个问题


Start by reproducing the issue with a DataX job that collects more than 300 tables, monitoring source and target database connections for lingering sleep sessions. Trace the connection lifecycle in the Java implementation and compare behavior across versions; done means connections are released after collection and the databases no longer accumulate sleeping sessions.
