* Build sample prior to code changes so differences are easier to decipher
* Add byte array type adapter for okhttp-gson (java8 only)
* Unit revealed that Gson (or GsonFire) defaults to escape = (equal sign) out of base64 string. Add disableHtmlEscaping() to gsonbuilder.
* Update specs and samples to include format=byte and include junit test of byte array serialization and deserialization.
* Implement recommendations by @cbornet including: Use okio.ByteString for base64 conversions instead of java 8 lib since the okhttp-gson client already includes okio. Remove setting to disableHtmlEscaping. Rename LocalByteArrayAdapter to ByteArrayAdapter.
* Update spec and sample for java okhttp-gson library client
* Undo addition of profilePhoto property. A format byte property is already available under the format_test definition.
* Put previously deleted tests back. Modified testFindPetsByTags() to verify exception since the server now returns a 500 for this request.
* Update test to pass when run against docker containerized server swaggerapi/petstore (heads up, this test fails if calling out to the internet published version of http://petstore.swagger.io)
* Closes#5863
The "dateLibrary" option for java, sadly, sets a mustache value "java8". This change updates this so that "java" in the mustache
libraries means what it should mean - use all java8 classes. In this case, there's no need for the third party Base64 library
as java8's JDK has this built in. In my view, the "dateLibrary" should be deprecated but that should be a separate PR.
* Closes#5954
