2. Installation Prerequisites 

Before installing Apache CXF, make sure the following products,
with the specified versions, are installed on your system:

    * Java 17 Development Kit
    * Apache Maven 3.x to build the samples


3.  Integrating CXF Into Your Application

If you use Maven to build your application, you need merely add
appropriate dependencies. See the pom.xml files in the samples.

If you don't use Maven, you'll need to add one or more jars to your
classpath. The file lib/WHICH_JARS should help you decide which 
jars you need.

4. Building the Samples

Building the samples included in the binary distribution is easy. Change to
the samples directory and follow the build instructions in the README.txt file 
included with each sample.

5. Reporting Problems

7. Specific issues, features, and improvements fixed in this version

** Bug
    * [CXF-9032] - JWK keystore type is not getting loaded if JWT contains x5t header
    * [CXF-9234] - Concurrent DynamicClientFactory.createClient for the same WSDL url corrupts the cached schema DOM and spins forever at 100% CPU
    * [CXF-9235] - Invocation.Builder.property() settings ignored by HTTP transport for set.content.type.for.empty.request
    * [CXF-9240] - OAuthJSONProvider.appendJsonPair() does not escape JSON string values — output injection / malformed JSON in introspect & token responses
    * [CXF-9241] - ImplicitConfidentialGrantService violates RFC 6749 §4.2.2 by issuing Refresh Tokens in the Implicit Flow
    * [CXF-9245] - Race Condition in ServerLifeCycleManagerImpl#stopServer()
    * [CXF-9250] - HttpClientHTTPConduit: failed exchange without request body is re-sent endlessly from the exceptionally callback (e.g. remote WSDL fetch)




** Improvement
    * [CXF-9233] - AbstractLoggingInterceptor.LIVE_LOGGING_PROP already set in the message properties, so RESP_OUT log is disable :(
