------------------------------------
Summary: ResourceInfo cannot be injected in OSGi environment
Key: CXF-6005
URL: https://issues.apache.org/jira/browse/CXF-6005
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 2.7.12
Reporter: Andrei Shakirin
Priority: Critical
Problem: by injection of ResourceInfo in resource class or in provider in OSGi
environment CXF throws following exception:
{code}
Caused by: java.lang.IllegalArgumentException: interface
org.apache.cxf.jaxrs.impl.tl.ThreadLocalProxy is not visible from class loader
at java.lang.reflect.Proxy.getProxyClass0(Proxy.java:487)[:1.7.0_40]
at java.lang.reflect.Proxy.newProxyInstance(Proxy.java:722)[:1.7.0_40]
at
org.apache.cxf.jaxrs.utils.InjectionUtils.createThreadLocalProxy(InjectionUtils.java:962)
{code}
Reason of the problem: there is no dedicated thread local context for
ResourceInfo and CXF instantiates it using java reflection proxy in
InjectionUtils:
{code}
return
(ThreadLocalProxy<T>)Proxy.newProxyInstance(type.getClassLoader(),
new Class[] {type, ThreadLocalProxy.class },
new ThreadLocalInvocationHandler<T>());
{code}
The problem is that classloader in first argument is taken from type class, but
proxy have to implement two interfaces: type and ThreadLocalProxy (second
argument). It works fine in standalone environment, but in OSGi classloader of
ResourceInfo bundle doesn't know nothing about ThreadLocalProxy interface in
CXF JAX-RS bundle. Of course, the ThreadLocalProxy cannot be found.
Solution: possible solution is use the classloader of current class
(InjectionUtils) instead of type class. As far as InjectionUtils classloader
knows type class as well it should work in standalone as well as in OSGi
environments.
