Sergey Beryozkin commented on CXF-6369: --------------------------------------- The change to isRegistered is fine, but I'm not sure about the 2nd one, I think it is sufficient to check if a given provider has already been registered and if yes then issue a warning as per the Java docs and return > org.apache.cxf.jaxrs.impl.ConfigurationImpl does not comply with SPEC > --------------------------------------------------------------------- > > Key: CXF-6369 > URL: https://issues.apache.org/jira/browse/CXF-6369 > Project: CXF > Issue Type: Bug > Components: JAX-RS > Affects Versions: 3.0.3, 3.0.4, 2.7.15 > Reporter: iris ding > > According to > http://docs.oracle.com/javaee/7/api/javax/ws/rs/core/Configurable.html > As a general rule, for each JAX-RS component class there can be at most one > registration — class-based or instance-based — configured at any given > moment. Implementations MUST reject any attempts to configure a new > registration for a provider class that has been already registered in the > given configurable context earlier. Implementations SHOULD also raise a > warning to inform the user about the rejected component registration. > For example: > config.register(GzipInterceptor.class, WriterInterceptor.class); > config.register(GzipInterceptor.class); // Rejected by runtime. > config.register(new GzipInterceptor()); // Rejected by runtime. > config.register(GzipInterceptor.class, 6500); // Rejected by runtime. > So we need to check whether the same class's instances have already been put > into config before hand. > Also to check whether the class/instance has been registered via public > boolean isRegistered(Class<?> cls) , we need to check whether the two class > is the same other than just isAssignableFrom. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
