----------------------------------

[~tangzhankun], 
I'm wondering if 
{code} 
82          if (resourcesStr.startsWith("[")) {         
83            resourcesStr = resourcesStr.substring(1);         
84          }           
85          if (resourcesStr.endsWith("]")) {           
86            resourcesStr = resourcesStr.substring(0, resourcesStr.length() - 
1);              
87          }
{code}
Should be removed.
