Regarding #4149 and against the better advice of #2623
Currently recursive functions only output this:

with the patch this becomes
"A StackOverflowError means that you have a bug that's causing a function
to be called recursively (it's calling itself and going in circles),
or you're intentionally calling a recursive function too much,
and your code should be rewritten in a more efficient manner."
(and the TimeoutException once you click the stop button)
This one goes from ASTGenerator on a background thread to the JList
which displays code suggestions. Until refactored, I'm making it
immutable with convenience methods returning mutated copies to prevent
possible threading issues.
Does not guarantee support for all Java 7 features (only some), but
warns about lambdas not being available. Lambdas are not supported,
because they make ANTLR angry.
Fixes#4034
The Arduino code would read one byte from the buffer an then sleep for 1/10th of a second, while Processing would send a byte every frame. Instead, read in all the bytes in the input buffer and act on the most recent one.
