Thanks a lot Andreas for these fixes. Now the Truffle API can truly be used on 
JDK 1.7!

This is exactly the "1.7.5 compatibility" one gets when compiling on JDK8 but 
using -source 1.7 that Gilles was referring to recently. Of course such code 
couldn't run on JDK7, but hopefully we'll never regress now when each commit 
is really compiled on JDK7 to verify real "1.7 compatibility".

Thanks for removing this class. It was an old idea of integrating JPDA 
debuggers with Truffle, but now, when we have 
http://lafo.ssw.uni-linz.ac.at/javadoc/truffle/latest/com/oracle/truffle/api/debug/Debugger.html
it is no longer need.

Thanks again for your help.
