 * DESCRIPTION
 *     Test provokes 'VMOutOfMemoryException'.
 *     Test scenario:
 *     Debugger obtains 'ArrayType' instance for int array and in endless loop instantiates arrays
 *     in debuggee VM through 'ArrayType.newInstance()' till VMOutOfMemoryException. Any other exception
 *     thrown by 'ArrayType.newInstance()' is treated as product bug.
