>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>    Affects Versions: 3.0.3.GA
>            Reporter: Manik Surtani
>            Assignee: Manik Surtani

> Could also help by making default config bundles, like Configuration.getDefaultLocalConfig(), getDefaultReplicatedConfig(), etc.
> From Bill Burke, who reported this:
> "
> Problem:
> This code did not work:
>      CacheFactory factory = new DefaultCacheFactory();
>      ExpirationAlgorithmConfig exp = new ExpirationAlgorithmConfig();
>      exp.setMaxNodes(maxSize);
>      EvictionRegionConfig evictionRegionConfig = new EvictionRegionConfig();
>      evictionRegionConfig.setEvictionAlgorithmConfig(exp);
>      EvictionConfig evictConfig = new EvictionConfig();
>      evictConfig.setDefaultEvictionRegionConfig(evictionRegionConfig);
>      evictConfig.setWakeupInterval(wakeupInterval);
>      Configuration config = new Configuration();
>      config.setCacheMode(Configuration.CacheMode.LOCAL);
>      config.setEvictionConfig(evictConfig);
> I got a NullPointerException at line 700 of RegionManagerImpl.  This is because I did not set the region FQN within the EvictionRegionConfig constructor.  There is no documentation to figure out how to do this.  I had to dig into source code to figure out the problem.  Also javadocs are not clear on what the default values are or how to assemble things.
