Rollback() on ClientAbortException, is it right?

I am working on JForum 2.1.8. In the method handleException() inside, a rollback is done when an exception is caught.
Further below in the method, there is a check that if the Exception was ClientAbortException, then it is not logged using ExceptionWriter.

I am trying to programmatically create a Forum from another application by using HttpURLConnection and passing appropriate forum creation parameters. I am getting random ClientAbortException from JForum. The above code in handleException() poses following problems:

1. A rollback is done, which means any data updated to db in this transaction is lost. (I have seen posts in other forums where it has been mentioned that this exception is not really a problem and can be ignored)
2. Since the exception is not logged anywhere, the failure mode is silent, so it took me lot of digging to find this problem.

If I move the rollback() call inside the if block like this:

if (e.toString().indexOf("ClientAbortException") == -1) {
because I do not want a rollback when my program connects to JForum via an HttpURLConnection and creates a forum, will there be any other impact on the system?

Thanks in advance
