I'm trying to figure this one out:
Person person = new Person();
| person.setHobbies(new HashMap());
| Iterator i = person.getHobbies().values().iterator();
|
| Util.getClusterCache().putObject("/test", person);
| person = (Person)Util.getClusterCache().getObject("/test");
|
| i = person.getHobbies().values().iterator();
| ...
| public static synchronized TreeCacheAop getClusterCache(){
| if(treeCache == null){
| try {
| treeCache = new TreeCacheAop();
| PropertyConfigurator config = new PropertyConfigurator(); //
configure tree cache.
| config.configure(treeCache, "META-INF/replSync-service.xml");
| treeCache.startService();
| } catch (Exception e) {
| traceLog.fatal("Error while initializing JBoss cache", e);
| }
| }
| return treeCache;
| }
Why does line 8 (.values.iterator()) cause a NullPointerException but line 3 doesn't?
