Change in behavior of javax.tools.JavaCompiler in JDK 8 running with -proc:only ?

[Jonathan Gibbons]

Boaz,

In JDK 8, javac is more aggressive about reporting errors (and stopping 
the compilation) if the errors cannot be fixed by running annotation 
processors. This should not be an issue if you are using anno processors 
for generating code.

What sort of errors are you seeing in your compilation?
