Bug Report: PDF Text extraction takes several minutes- with 100% CPU

We use Aspose for text extraction purposes only, on Java.

On some of our machines, the text extraction for a small document takes several minutes, with 100% CPU and locking other threads, whereas it is very fast on others. The reason is simple: Aspose.pdf looks for font directories in a given list. The list is the following:















But, if none of these directories exist (this is disturb-dependent), then the fallback becomes “/” ! As a result, one thread scans the full hard-drive, locking all the other…

This results in a several minutes 100% CPU activity, but everything locked.

The workaround is simple, create an empty “.fonts” directory in the home dir of the user executing the application. But I clearly think this should be considered as a bug !
