There are two problems:
1) Inability to evaluate classes that were not loaded in the VM yet and this is described in bug #168949.

2) Inability to create brand new classes during evaluation
   E.g. evaluate "new Runnable() { public void run() { ...}}".

The second case would be necessary when evaluating a lambda expression.

For lambdas, there might be a solution...

Having re-read the rest of the comments I now see that the first issue was fixed, but the second one was not. That is, this issue was probably never working in 8.2 and is a RFE. I'm going to update this issue accordingly. I still believe that this issue is high priority as adding watches for lambdas is a very common use-case nowadays.)
