/**
 * <p>{@link javax.cache.annotation.CacheRemove} interceptor implementation.This interceptor uses the following algorithm describes in
 * JSR-107.</p>
 *
 * <p>The interceptor that intercepts method annotated with {@code @CacheRemoveEntry} must do the following, generate a
 * key based on InvocationContext using the specified {@link javax.cache.annotation.CacheKeyGenerator}, use this key to remove the entry in the
 * cache. The remove occurs after the method body is executed. This can be overridden by specifying a afterInvocation
 * attribute value of false. If afterInvocation is true and the annotated method throws an exception the remove will not
 * happen.</p>
