This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
I created a new library, then attempted to explore classes in this library on my machine. I have copied this class Base64.class to several locations to see if my application will recognize it. Netbeans shows a wierd ICON for this file, and then gives this abort. (it may be some kind of permissions problem, or windows file lock problem, but I can't see any).

This is an MDR issue, not classfile.
I am closing all reports in category Java/Unsupported as wontfix. These should be dead issues --- if the reported cases are against some live part of the NetBeans IDE please reopen and we can discuss to which category they belong.
