Write timeout does not work for JDO update operations

[smatytsin]

As described in documentation there are few settings to set Read/Write timeouts for DB Requests:
javax.jdo.option.DatastoreReadTimeoutMillis
javax.jdo.option.DatastoreWriteTimeoutMillis
datanucleus.datastoreWriteTimeout
datanucleus.datastoreReadTimeout

But WriteTimeout does not work if DB Request is inited by JDO update event.
When we update a state of JDO object, the executeUpdate request calls without any timeout set for PreparedStatement

Here is a callstack (for old 4.1.19 release but problem is also actual for newest releases):
