[jboss-dev-forums] [Design the new POJO MicroContainer] - Careful with default serialization, JBVFS-17

[scott.stark@jboss.org]

The serialization of the NestedJarFromStream is incorrect. Its using default serialization of these fields:

   private transient ZipInputStream zis;
   private URL jarURL;
   private URL entryURL;
   private long lastModified;
   private long size;
   private AtomicBoolean inited = new AtomicBoolean(false);

The problem is that the inited flag should not be serialized as this implies its parents fields:

   private transient List entries;
   private transient Map<String, VirtualFileHandler> entryMap;

have been initialized. They will not be after deserialization of NestedJarFromStream as it lazily does initialization. We need to be careful when adding fields to a class that is using the default java serialization contract.
