Summary: Exception - expecting EOF still in version 4.3

Initial Comment:
The following class causes an exception in checkstyle 4.3, at least with eclipse-cs 4.3.0 plugin:
package foo.bar;

import java.util.List;

interface Foo {
    public <T> List<T> bar(T foobar);

public class CheckstyleBug {

    public void foo() {
        Foo foo = new Foo() {
            public <T> List<T> bar(T foobar) {
                return null;

If the anonymous inner class is converted to a real class, the exception disappeares.

The log file contains:
!ENTRY com.atlassw.tools.eclipse.checkstyle 1 0 2007-02-23 16:41:09.342

!MESSAGE Checkstyle-Plugin: RecognitionException occured.

We are looking into adopting checkstyle but hitting this on several classes
as well (which will sadly prevent adoption).  It would be awesome to get a
new version out with the patch referenced from the previous comment applied
(assuming it works of course).

This is still present in 5.3. The following code reproduces the error:

class CheckstyleIsBroken {

    void checkstyleIsBroken() {
        CheckstyleIsBroken borkage = new CheckstyleIsBroken() {

            <T extends CheckstyleIsBroken> T borked(T brokenness) {
                return brokenness;

There are 2 problems here.
For the generics problem, in (line 2311 of mine)
checkstyle-4.4, in the typeParameters method, it wants to read:
  if (!(isThereASingleGtToEmit()) && inputState.guessing == 0)
rather than:
  if (!(isThereASingleGtToEmit()))

For the second problem, there is a missing case: COMMA in the
arrayInitializer method (line 4533 in mine).
(in line 4621) works.

I'm still seeing the original bug with a generic method in Checkstyle 4.4.

I am getting the same error in Checkstyle 4.4 from this piece of code:

public class CheckstyleBug {
    public static void main(String[] args) {
        int[] myArray = new int[] { , };

Checkstyle aparently gets confused by the odd (but valid) expression "{ ,
