They're related to JavaBeans -- I believe there's a feature of the plugin that allows you to wrap a Java Bean as an ActiveX control, so there's a pile of code that treats JavaBeans like applets.  As a security measure you don't want components reading from or writing to each others streams, so this is how they keep them separate.

That's a 10-minute reading-of-the-code analysis, so I may be wrong.  But, you're implementation sounds like it matches what's in the plugin.  I doubt it will ever get used, though.
