 public Class<?> fastFindClass( final String name ) {
            lock.lock();
            Class<?> cls = findLoadedClass( name );

            if (cls == null) {
                    final byte[] clazzBytes = this.store.read( convertClassToResourcePath( name ) );
                    if (clazzBytes != null) {
                        String pkgName = name.substring( 0,
                                                         name.lastIndexOf( '.' ) );
                        if ( getPackage( pkgName ) == null ) {
                            definePackage( pkgName,
                                           "",
                                           "",
                                           "",
                                           "",
                                           "",
                                           "",
                                           null );
                        }

                        cls = defineClass( name,
                                           clazzBytes,
                                           0,
                                           clazzBytes.length,
                                           PROTECTION_DOMAIN );
                    }

                    if (cls != null) {
                        resolveClass( cls );
                    }
                }


            lock.unlock();
            return cls;
        }


it that ok? i  find the lock has been removed in 6.2.0.Final， is that means 5.6.0Final has dead lock problem？ can i use 5.6.0 in my project?
