[jboss-jira] [JBoss JIRA] (JBAS-9399) URL.getContent() returns VirtualFile instead of ImageProducer in JBoss AS 6.0.0.FINAL

[Nathan Blomquist (JIRA)]

    [ https://issues.jboss.org/browse/JBAS-9399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13603272#comment-13603272 ] 

Nathan Blomquist commented on JBAS-9399:
----------------------------------------

The workaround that was added isn't really a workaround for this.  The issue is that on a standard JVM (non-JBoss), the SimpleBeanInfo.class works fine.  On JBoss the class fails.

The SimpleBeanInfo.class is a Java library class. 
https://docs.oracle.com/javase/7/docs/api/java/beans/SimpleBeanInfo.html

In our case it was used in a third party component for which we didn't have code access.  We actually weren't trying to get the image and didn't care about the image.  The third party component tried to load it during construction.

> URL.getContent() behaves differently within JBoss than it does in a normal JVM.  In our case, when a jar is used in a normal JVM, URL.getContent() returns an ImageProducer.  When the same jar is used from within JBoss, a VirtualFile is returned which then causes a ClassCastException.
> Note: This worked fine in JBoss 4.2.3.GA.
