Example 31 with RVMArray

use of org.jikesrvm.classloader.RVMArray in project JikesRVM by JikesRVM.

the class MemoryManagerTest method allocateArrayTestOverflowToNegative.

@Test(expected = OutOfMemoryError.class)
public void allocateArrayTestOverflowToNegative() {
    int size = 1 << 29;
    RVMArray arrayType = RVMArray.IntArray;
    int headerSize = ObjectModel.computeArrayHeaderSize(arrayType);
    int align = ObjectModel.getAlignment(arrayType);
    int offset = ObjectModel.getOffsetForAlignment(arrayType, false);
    int width = arrayType.getLogElementSize();
    TIB arrayTib = arrayType.getTypeInformationBlock();
    int[] test = (int[]) MemoryManager.allocateArray(size, width, headerSize, arrayTib, ALLOC_NON_MOVING, align, offset, DEFAULT_SITE);
