我刚看了源码
PoolInterceptor
private List isPoolableCache = new ArrayList();

这个 public boolean isPoolabe(TargetMetaDef targetMetaDef) {
boolean found = false;
if (isPoolableCache.contains(targetMetaDef.getName())) {
found = true;
}else if(!unPoolableCache.contains(targetMetaDef.getName())){
Debug.logVerbose("[JdonFramework] check if it is a Poolable", module);
ContainerWrapper containerWrapper = containerCallback.getContainerWrapper();
Class thisCLass = containerWrapper.getComponentClass(targetMetaDef.getName());
if (Poolable.class.isAssignableFrom(thisCLass)) {
found = true;
isPoolableCache.add(targetMetaDef.getName());
}else{
unPoolableCache.add(targetMetaDef.getName());
}
}
return found;
}
isPoolableCache.contains这个和add在并发下会出现越界
contains里面实际上是调用的indexOf,这个是循环size通过下标访问数据进行比较。有可能会发生当前size是10个，这个时候我们在调用contains这个时，然后按照size是10循环小标，然后这个时候其他地方把数据删除一个，变成9，那么在循环到10的时候，那么就会越界。

我看到最新的版本和以前的版本都有这个问题，我现在把
private final List isPoolableCache = new CopyOnWriteArrayList();改成这样就好了。就没出现了
