Subject [jira] Commented: (YOKO-258) Bad reference to ClassLoader.classes in org.apache.yoko.rmi.util.ClassLoaderLocal static initializer

Sergey Salishev commented on YOKO-258:
--------------------------------------

Oops. I've run the simple test and it shows it's possible to change the the content ClassLoader
at any time tin Thread life cycle. I thought it can be changed only before the thread is started.
I was wrong. 

So the only ways to correct the fix I see now are ether synchronize the localMaps access or
use fine grained hash map from java.util.concurent

> org.apache.yoko.rmi.util.ClassLoaderLocal class contains the following line in its static
initializer:
> 	classes_vector = ClassLoader.class.getDeclaredField("classes");
> This line references the 'classes' field in class java.lang.ClassLoader, and that field
is not documented by API JavaDoc and may be absent in particular Java VM/classlib implementations,
for example it's absent in Apache Harmony.
> As the result of this issue, the classes org.apache.yoko.rmi.util.ClassLoaderLocal and
org.apache.yoko.rmi.impl.PortableRemoteObjectExtImpl fail to load with NoSuchFieldException,
on those implementations.
