I think there's one underlying issue here - which is a difference in the 
way shadowing for type-varables is handled in javac w.r.t. to Eclipse. 
When two names are available, a class name and a type-variable name 
respectively, javac seems to prefer the class name - this results in 
your first bug - as a type-variable cannot be referenced from static 
context, and in this reflection glitch.

I think some work as been done on this early in JDK 7 - see [1]; 
unfortunately the fix seems to be incomplete; it only addresses the very 
specific issue raised in that very same bug report (shadowing within 
type-variable declaration), and not the wider issue of scoping of 
type-variables vs. class names.
