> Key: QPID-8601
> URL: https://issues.apache.org/jira/browse/QPID-8601
> Project: Qpid
> Issue Type: Improvement
> Components: Broker-J
> Affects Versions: qpid-java-broker-8.0.6
> Reporter: Daniil Kirilyuk
> Priority: Minor
>
> Broker model objects heavily rely on java reflection.
> Java version 7/8 introduced reflection alternatives allowing to access class
> fields as well as call class methods. Brief review of those alternatives can
> be found in this [blog
> post|https://www.optaplanner.org/blog/2018/01/09/JavaReflectionButMuchFaster.html].
> There are further changes coming, e.g. [JEP 416|https://openjdk.org/jeps/416]
> (implemented in Java 18), having as a goal reimplementation of
> java.lang.reflect.Method, Constructor, and Field on top of java.lang.invoke
> method handles. Jackson databind library already has an
> [issue|https://github.com/FasterXML/jackson-databind/issues/2083] directed to
> replace reflection calls with method handles. Similar approach is used in
> [spring
> data|https://github.com/spring-projects/spring-data-commons/blob/main/src/main/java/org/springframework/data/mapping/model/ClassGeneratingPropertyAccessorFactory.java]
> framework as well.
> We suggest to implement a static instrumentation object, which will replace
> reflection method invocation with the invocations of static final
> MethodHandle instances.
