How can I diagnose class loading problems?
See this blog.
What's a uses constraint and what can I do if one is violated?
Uses constraints are explained in this blog.
Virgo typically produces helpful diagnostics for uses constraint violations. To solve uses constraint violations, see Rob Harrop's blog and Neil Bartlett's blog.
How can I import a package into someone else's bundle without hacking the manifest?

What support does Virgo have for thread context class loaders?
See this blog.
How can I get a graphical application to work in Virgo?
To get GUI apps to work in Virgo, you have to edit lib/java6-server.profile in order to add some packages to the org.osgi.framework.bootdelegation property.
On Mac, you need to add some Apple packages:
org.osgi.framework.bootdelegation = \
org.eclipse.virgo.osgi.extensions.*,\
org.eclipse.virgo.osgi.launcher.*,\
org.eclipse.virgo.kernel.authentication,\
com.sun.*,\
javax.xml.*,\
org.apache.xerces.jaxp.*,\
org.w3c.*,\
org.xml.*,\
sun.*,\
apple.*,\
com.apple.*
On Windows, you just need to add com.sun.* as sun.* is already in the list.
org.osgi.framework.bootdelegation = \
org.eclipse.virgo.osgi.extensions.*,\
org.eclipse.virgo.osgi.launcher.*,\
org.eclipse.virgo.kernel.authentication,\
com.sun.*,\
javax.xml.*,\
org.apache.xerces.jaxp.*,\
org.w3c.*,\
org.xml.*,\
sun.*,\
com.sun.*
