CAS heap doesn't grow correctly when first page exceeded
--------------------------------------------------------
Key: UIMA-440
URL: https://issues.apache.org/jira/browse/UIMA-440
Project: UIMA
Issue Type: Bug
Components: Core Java Framework
Affects Versions: 2.1
Reporter: Adam Lally
Priority: Critical
Fix For: 2.2
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.
