Comments
EVALUATION The sun.misc.* classes are filtered out in DownloadManager, due to the fact that they are all included and it causes problems for DownloadManager to be asked about its sun.misc dependencies while it's still in the middle of initializing. The resources subpackage was unfortunately being hit by the same filter, despite not being part of the core -- so none of them could ever be loaded. I changed the sun/misc/* rule to sun/misc/..., so these classes are likewise part of the core.
