----------------------------
Resolution: Fixed
> When parsing an aggregate descriptor, should parse a shared type system file
> only once

> Key: UIMA-1230
> URL: https://issues.apache.org/jira/browse/UIMA-1230
> Project: UIMA
> Issue Type: Improvement
> Components: Core Java Framework
> Affects Versions: 2.2.2
> Reporter: Adam Lally
> Assignee: Adam Lally
> Priority: Minor
> Fix For: 2.3
>
>
> Frequently an aggregate will contain several primitives that all import a
> single shared type system descriptor. Currently, the shared type system
> descriptor will be separately parsed for each of the primitives, and each
> primitive descriptor will contain a separate copy of the
> TypeSystemDescription object.
> When there are a large number of primitives and a large number of types in
> the shared type system, this parsing takes a long time and the resulting
> TypeSystemDescription objects consume a lot of memory.
> Instead, we could keep a cache of imports that have already been parsed, and
> we can reuse the same TypeSystemDescription object within each of the
> primitive descriptors rather than having a separate copy.
