reckart opened a new issue, #215:
URL: https://github.com/apache/uima-uimafit/issues/215

   **Is your feature request related to a problem? Please describe.**
   The `TypeSystemDescriptionFactory` and similar classes cache descriptors on a per-classloader level. In cases where there are many dynamically created classloaders, this forces many re-scans and in particular re-parsings.
   
   **Describe the solution you'd like**
   Extend the caching mechanism such that pre-parsed descriptors are stored for each of the discovered locations. That way we cannot save on the scanning, but if the same location is discovered again at a later time, at least we could already have the pre-parsed and pre-resolved type system for that locating lying around in memory and ready to be merged into the final result. This would tremendously speed things up.
   
   **Describe alternatives you've considered**
   Reduce the number of classloaders in the target scenario - which is an option, but there may still be more than the uimaFIT caching can currently deal with in a swift manner.
