使用的是哪个版本？

[hongbiangoal]

1.6.6

[Jacksgong]

@hongbiangoal 确定清楚版本，这个问题在 #669 中修复过，我刚刚重新检查了代码，在1.6.2之后就不可能再遇到该问题。

[Jacksgong]

有任何反馈该Issue将被重新打开。

[hongbiangoal]

DefaultDatabaseImpl类的findConnectionModel方法中

model.setStartOffset(c.**getInt**(c.getColumnIndex(ConnectionModel.START_OFFSET)));
model.setCurrentOffset(c.**getInt**(c.getColumnIndex(ConnectionModel.CURRENT_OFFSET)));
model.setEndOffset(c.**getInt**(c.getColumnIndex(ConnectionModel.END_OFFSET)));

我改成getLong就ok了

[Jacksgong]

@hongbiangoal 抱歉，确实存在该问题，我这边会提交一个新版本修复这个问题。
