Why do I keep getting “Evaluations must contain either an expression or a block of well-formed statements”?

Question

In my code, I am trying to output the value of src in the expressions window.

public void doIt() {
    String src = \"test\";
    System.out.pri

If your code use any generics, you may want to check this bug:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=341232

Occurs in all version of Eclipse up to 4.2. In short certain generics expressions cause Eclipse to completely fail on any evaluation (please see this example: https://bugs.eclipse.org/bugs/attachment.cgi?id=224760). Not sure whether your code uses any generics, but if so, this may be it. Note that it is enough to have one of the troublesome generics somewhere in your class, not necessary in your method.
