Summary: Bug in LineNumberReader.java

Initial Comment:
I was trying to run an app and got an exception that
looked like this:

    java.io.IOException: Pushback buffer is full
            at
java.io.PushbackReader.unread(PushbackReader.java:319)
            at
java.io.LineNumberReader.read(LineNumberReader.java:246)
            ...

This appears to be a bug in LineNumberReader.java,
which the
patch below seems to fix.
