Failure in coverage plugin (NumberFormatException)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Running coverage with a reasonably large .js file. Can't really isolate the 
cause more than that.
2.
3.

What is the expected output? What do you see instead?

Expected test results and coverage data. Instead got a failure. Stack trace:

Failures during test run.

What version of the product are you using? On what operating system?

Using latest head (built on OS X)

Please provide any additional information below.

Smaller test cases are working fine.

What's reasonably large?

I don't think it is necessarily size related. I am testing a JS library (about 
50k). Simple tests that use about 40% of the code work. I tried a test that 
exercises much more of the code and had this problem.

Here is some test code that caused a repro. If I included the first queue.defer 
below I had no problem; if I included both then I got a barf. It doesn't really 
seem to have an obvious trigger as these are identically structured tests:

    queue.defer(function(pool) {
        Syn.click({}, 
            cbox, 
            pool.add(
                function() {
                    assertEquals(false, model.checked);
                    assertEquals(false, cbox.checked);
                }
            ));
    });

    // click again

    queue.defer(function(pool) {
        Syn.click({}, 
            cbox, 
            pool.add(
                function() {
                    assertEquals(true, model.checked);
                    assertEquals(true, cbox.checked);
                }
            ));
    });
