>          Issue Type: Improvement
>          Components: Core Java Framework
>    Affects Versions: 3.0.2SDK
>            Reporter: Marshall Schor

> When migrating to UIMA v3, code might inadvertently cause some feature structures (FSs)
to be pinned in memory, typically by producing some int value that could be used to retrieve
the FS.  If pinned, a FS cannot be garbage collected.
> Turning on this -D flag will produce a report of where code is pinning FSs.
