Javalang doesn't support Java8 default keyword.

[roipoussiere]

Let this simple Java8 code:

public interface Test{ default void save() {} }

which works according to javac:

echo "public interface Test{ default void save() {} }" > Test.java
javac Test.java

But javalang throws a Syntax error. Here working in a clean virtual env., tested both with Py2 and Py3:

import javalang
tree = javalang.parse.parse("package javalang.brewtab.com; public interface Test{ default void save() {} }")

Traceback (most recent call last):

It seems this set should contains 'default' to support Java8.

Thank you for this quick fix!

[roipoussiere]

Well, not really fixed. :-)
