Hello,

We are also facing similar issue while calculating page count. We are running this code under IBM WAS server and it is not specific to one file. It is failing with all pdf files:

Hi Robert,


<span style=“font-size:10.0pt;font-family:“Arial”,“sans-serif”;

other priority issues and I am afraid the above stated problem is not yet

Can you provide status on PDFNEWJAVA-33673 ?

Thank you.

Hi,

I am afraid the issue is not yet resolved. Please note that as a normal rule of practice, issues are resolved in first come and first serve basis; but the problems logged/reported under Enterprise or Priority support model, have high precedence in terms of resolution, as compare to issues under normal/free support model.

In case you need to have your issue prioritized, you may consider opting for Enterprise or Priority support options. Nonetheless, note that ES/PS support does not guarantee any immediate resolution of issues (because it might be dependent on other issues or feature which needs to be implemented) but under this model, the development team starts investigating the problem on high priority. For further details, please visit Support Options.

We are sorry for this delay and inconvenience.

Please advise how to escalate this issue to Enterprise support. We purchased the Enterprise license but I do not have access to the Enterprise forums.

Also keep in mind this issue was opened on 8/21/2013 so the clock should not "reset".

Thank you.

Hi,

In order to access Enterprise Support forum, you need to log-in through the username against which you have purchased ES support. Did you purchase the ES against your current boadean username or with any other name ? Please share some details, so we may further look into this matter.

boadean:
Also keep in mind this issue was opened on 8/21/2013 so the clock should not “reset”.

Once you are logged in with ES username, you can request to raise the priority of earlier reported issue in ES forums and we will increase its priority in Issue tracking system. Nonetheless, the issue will then be investigated and resolved on high priorities. We are sorry for your inconvenience.

The issues you have found earlier (filed as PDFNEWJAVA-33673) have been fixed in Aspose.Pdf for Java 10.4.0.
