Description

This test case (which I''ll check i under this issue) demonstrates the issue:

for (int j = 0; j < 10; j++) {
for (int i = 0; i < 200000; i++)

{ cas.createAnnotation(annotType, i, i); }

heapSize = ((CASImpl) cas).getHeap().getCurrentTempSize();
bufSize = ((CASImpl)cas).getHeap().heap.length;
//System.out.println("Heap size: " + heapSize + ", buffer size: " + bufSize);
assertTrue(heapSize <= bufSize);
Assert.assertTrue(bufSize < CASImpl.DEFAULT_RESET_HEAP_SIZE);
cas.reset();
}

The CAS should grow by one page initially (to 1,000,000 cells), but then should stay at that size. But this test fails. The output of the System.out.println is:
Heap size: 800008, buffer size: 1500000
Heap size: 800008, buffer size: 2000000
Heap size: 800008, buffer size: 2500000
Heap size: 800008, buffer size: 3000000
Heap size: 800008, buffer size: 3500000
Heap size: 800008, buffer size: 4000000
Heap size: 800008, buffer size: 4500000

The heap seems to be growing by one page each time.
