 * @summary converted from VM Testbase nsk/jvmti/Allocate/alloc001.
 * VM Testbase keywords: [jpda, jvmti, noras, nonconcurrent]
 * VM Testbase readme:
 * DESCRIPTION
 *     The test exercise JVMTI function Allocate(size, memPtr).
 *     The test checks the following:
 *       - if JVMTI_ERROR_NULL_POINTER is returned when memPtr is null
 *       - if allocated memory is available to access
 *       - if JVMTI_ERROR_OUT_OF_MEMORY is returned when there is
 *         insufficient memory available
 * COMMENTS
 *     Ported from JVMDI.
 *
 * @library /vmTestbase
 *          /test/lib
 *
 * @comment Not run on AIX as it does not support ulimit -v
 * @requires os.family != "aix"
 * @run main/native nsk.jvmti.Allocate.alloc001.alloc001
