Additional Java 5 Syntax Highlighting Errors in DrJava

While adding syntax highlighting for underscores and binary literals introduced in Java 7 to DrJava, I discovered that a few other numbers aren’t syntax-highlighted correctly. Some of these problems go back to the beginning of Java, others go back to Java 5, when the obscure hexadecimal floating-point literal was introduced.

Here are the numbers that give DrJava’s syntax highlighter trouble:

Did you know about these hexadecimal floating-point literals? I didn’t.

I created a bug report for these Java 5 highlighting bugs.
