I just ran the latest CPD [ PMD 1.05 ]

It is considerably much faster than previous version. I just ran the test in JDK src files and it ran in 1 min 39 seconds.

However, I noticed that it eats up a lot memory. Initially, I had java's maximum memory to "254MB" but I would run out memroy. So I had to up the java's maximum memory to 512 MB.

    Yup, props to Brian Ewins for his rewrite.

    True. One way to reduce the memory usage would be to avoid holding all the source files in memory... I just don't think anyone's gotten around to working on that, though...
