that I need the IE agent settings, and I really don't want to masquerade as
IE.

Widgets can be subclassed in dire circumstances [sic] by overriding the
checkSubclass() method to do nothing. A decorator would not really be any
more helpful.
However, the report's attached solution utilizes the Browser's "auto" field,
which is only visible to classes within the org.eclipse.swt.browser package.
So if you added your subclass to this package then it should be workable.
But then again, if you're looking at locally modifying your swt anyways, you
could just change your Browser implementation to incorporate the report's
changes.

Yes, this should work. Just be sure that the Browser.class and all of its
accompanying Browser$?.class files make it in.

was flawed because the server even blocked the IE agent.
