There must be a very good reason why we complicated our lives with all these technologies ... arguably that is freedom for something. Freedom might be a right but it is never free; so let me demonstrate how I earned it.

"com.salesforce.ide.api.metadata.types.Metadata$JaxbAccessorF_fullName cannot be cast to com.sun.xml.bind.v2.runtime.reflect.Accessor"
Saw that on my newly installed Juno when I tried to refresh Force.com projects (or pretty much everything else after that). There's some discussion with no definitive answer (various workarounds work for various users). For me it's fixed by using JVM 1.6 instead of 1.7 (update 21).
