Re: [jboss-dev] Infinite loop during shutdown

Tuesday, 29 June 2010

Its a bug. There's a missing check for null before calling the
ClassFoundHandler

But thats not the whole issue. Its another example of the logging wanting to
load
a class but that fails and the classloader wants to do some logging to
report the problem.

The logging should not be lazy loading its classes, otherwise if an error
occurs
during that (or you just turn up the classloader logging to TRACE) it is
probably going to loop.

In BaseClassLoader (the result can be null if it fails to open to the
stream)

   synchronized Class<?> loadClassLocally(final String name, final
boolean trace)
   {
      if (trace)
         log.trace(this + " load class locally " + name);

      // This is really a double check but the request may not have
entered through loadClass on this classloader
      Class<?> result = isLoadedClass(name, trace);
      if (result != null)
         return result;

      // Look for the resource
      final String resourcePath = ClassLoaderUtils.classNameToPath(name);

      result = AccessController.doPrivileged(new PrivilegedAction<Class<?>>()
      {
         public Class<?> run()
         {
            InputStream is = policy.getResourceAsStream(resourcePath);
            if (is == null)
            {
               if (trace)
                  BaseClassLoader.log.trace(BaseClassLoader.this + "
resource not found locally " + resourcePath + " for " + name);
               return null;
            }

            // Load the bytecode
            byte[] byteCode = ClassLoaderUtils.loadByteCode(name, is);

            // Let the policy do things before we define the class
            BaseClassLoaderPolicy basePolicy = policy;
            ProtectionDomain protectionDomain =
basePolicy.getProtectionDomain(name, resourcePath);
            try
            {
               byte[] transformed = policy.transform(name, byteCode,
protectionDomain);
               if (transformed != null)
                  byteCode = transformed;
            }
            catch (Throwable t)
            {
               throw new RuntimeException("Unexpected error
transforming class " + name, t);
            }

            // Create the package if necessary
            URL codeSourceURL = null;
            if (protectionDomain != null)
            {
               CodeSource codeSource = protectionDomain.getCodeSource();
               if (codeSource != null)
                  codeSourceURL = codeSource.getLocation();
            }
            definePackage(name, codeSourceURL);

            // Finally we can define the class
            Class<?> result;
            if (protectionDomain != null)
               result = defineClass(name, byteCode, 0,
byteCode.length, protectionDomain);
            else
               result = defineClass(name, byteCode, 0, byteCode.length);
            if (trace)
               BaseClassLoader.log.trace(BaseClassLoader.this + "
loaded class locally " + ClassLoaderUtils.classToString(result));
            return result;
         }
      }, policy.getAccessControlContext());

+ if (result != null)
+ {
      loadedClasses.add(name);
      policy.classFound(new ClassFoundEvent(this, result));
+ }

      return result;
   }

 It appears I've run into an infinite loop on shutdown (or at

 something that looses my patience).
