[shrinkwrap-issues] [JBoss JIRA] Commented: (SHRINKWRAP-237) ShrinkWrap ClassLoader Caches the read Assets Inputstream

[Dan Allen (JIRA)]

    [ https://jira.jboss.org/browse/SHRINKWRAP-237?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12559466#action_12559466 ] 

Dan Allen commented on SHRINKWRAP-237:
--------------------------------------

Aslak, I'm not sure what you are getting at. Are you saying this is not an issue? I ran into the same problem testing the descriptors project. If I try to read in a descriptor two times in a row, even if I close the stream, the second time I get an EOF. We can't assume that developers will only ever read a resource once.

I'll clarify my use case with an example. If I do this operation twice, the second time will fail.

InputStream is = getResourceAsStream(name);

if (is != null)
{
   try
   {
      return Descriptors.importAs(descriptorType).from(is);
   }
   finally
   {
      // NOTE the import process should really be closing the stream
      try
      {
         is.close();
      }
      catch (IOException e)
      {
         // Nothing we can do about this
       }
   }
}

> This can be reproduced using Weld 1.1.0.Beta1, Seam XML Alpha3 and Arqullian Alpha4-  create a test that attempts to add a Manifest Resources from disk to Beans.xml.
> Seam XML will attempt to load the beans file and complain that the InputStream was closed.
