Issue

When converting a java file which contains the following the conversion fails:

static final int FLAG_LONG_FRAME = 0b10;
static final int FLAG_COMMAND_FRAME = 0b100;

System.FormatException: Additional non-parsable characters are at the end of the string.

Changing the constants in the java class to regular decimal representation ( = 1;) fixes the issue

Version

This was already fixed in 4.0.0-beta via #83, but I added additional test coverage in #158 too. Going to finish cleaning up some of these open issues and then get a 4.0.0 final release out.
