Support google collections ImmutableMaps with stripes:options-map
-----------------------------------------------------------------
Key: STS-730
URL: http://www.stripesframework.org/jira/browse/STS-730
Project: Stripes
Issue Type: Improvement
Components: Tag Library
Affects Versions: Release 1.5.2, Release 1.5.1
Environment: any
Reporter: Nathan Feger
google's collections API makes for a very novel way to make immutable maps:
http://code.google.com/p/google-collections/
http://google-collections.googlecode.com/svn/trunk/javadoc/com/google/common/collect/ImmutableMap.html
Map:
public static final Map<String, String> MAP = new ImmutableMap.Builder<String,
String>()
.put("abc", "xyz")
.put("key2", "value2")
.build()
However, when the tag attempts to read the key and value out of the
ImmutableEntry class (that extends Map.Entry) it throws an exception:
2009-12-08 11:00:46,817 ERROR [http-8080-Processor25]

Not supporting the google collections probably won't end the world, but they
are surprisingly nice to work with.
