// TODO: {dlf} this test currently doesn't test anything!
// You'll notice that the resource that uses the dictionary isn't even on the resource path,
// so the dictionary never gets used. Good thing, too, because it would throw a security
// exception if run with a security manager. Not that it would matter, the dictionary
// resource isn't even in the icu source tree!
// In order to fix this:
// 1) make sure english.dict matches the current dictionary format required by dbbi
// 2) make sure english.dict gets included in icu4jtests.jar
// 3) have this test use getResourceAsStream to get a stream on the dictionary, and
// directly instantiate a DictionaryBasedBreakIterator. It can use the rules from
// the appropriate section of ResourceBundle_en_US_TEST. I'd suggest just copying
// the rules into this file.
// 4) change the test text by inserting '|' at word breaks, and '||' at line breaks.
// 5) process this text to a) create tables of break indices, and b) clean up the test
// for the break iterator to work on
//
// This would NOT test the ability to load dictionary-based break iterators through our
// normal resource mechanism. One could install such a break iterator and its
// resources into the icu4j jar, and it would work, but there's no way to register entire
// resources from outside yet. Even if there were, the access restrictions are a bit
// difficult to manage, if one wanted to register a break iterator whose code and data
// resides outside the icu4j jar. Since the code to instantiate would be going through
// two protection domains, each domain would have to allow access to the data-- but
// icu4j's domain wouldn't know about ours. So we could instantiate before registering
// the break iterator, but this would mean we'd have to fully initialize the dictionary(s)
// at instantiation time, rather than let this be deferred until they are actually needed.
//
// I've done items 2 and 3 above. Unfortunately, since I haven't done item 1, the
// dictionary builder crashes. So for now I'm disabling this test. This is not
// that important, since we have a thai dictionary that we do test thoroughly.
