It's a generic adjective that means different things for different people. There's no measure of robustness, so you can't say "this language is more robust than that".

It might be used to differentiate a language from a "toy" language, that isn't meant for general purpose programming, but you aren't going to find any clear definitions, because there isn't one.

Javanotes 9, Section 8.1 -- Introduction to Correctness and Robustness
So you see that not all possible errors are avoided or detected automatically in Java. Furthermore, even when an error is detected automatically, the system's default response is to report the error and terminate the program. This is hardly robust behavior! So, a Java programmer still needs to learn techniques for avoiding and dealing with errors.
