Review Comment:
Our unit test could not pass if is 0 here, the key point seems that if we
should support such usage:
```bash
openTransaction()
// new function1
{
openTransaction()
commitTransaction() # place1
}
// new function2
{
openTransaction()
commitTransaction()
}
commitTransaction() # place2
```

Review Comment:
If commit throw RuntimeException, it should call rollback in the finally
block of previous layer where the openTransactionCalls would be decreased.

Review Comment:
It may throw exception, so we need such logic:
```java
try {
openTransaction();
success = commitTransaction();
} finally {
if (!success) rollbackTransaction();
}
```
