--------------------------------------
Summary: AbstractRegexExtensionExtractor needs to fix memory
reference issue
Key: STREAMS-182
URL: https://issues.apache.org/jira/browse/STREAMS-182
Project: Streams
Issue Type: Bug
Reporter: Robert Douglas
The ensureTargetObject function in AbstractRegexExtensionExtractor does not
always ensure that the collection it returns is the collection that was
originally pointed to by the extensionKey.
once the hashtags set has been created (either via
Sets.newHashSet((Iterable<T>) extensions.get(extensionKey)) or
Sets.newHashSet() depending on if it was already present) then it needs to be
reassigned to the extensionKey. This will make sure that any modifications to
the hashtags Set will be reflected in the final Activity Object
