org.eclipse.daanse.olap/common/src/main/java/org/eclipse/daanse/olap/util/ArrayStack.java should be replaces with ArrayDeque

[dbulahov]

Current Behavior

org.eclipse.daanse.olap/common/src/main/java/org/eclipse/daanse/olap/util/ArrayStack.java uses now.

Expected Behavior

org.eclipse.daanse.olap/common/src/main/java/org/eclipse/daanse/olap/util/ArrayStack.java

this can be replaces with ArrayDeque

start with testijng in unit test then replace in

org.eclipse.daanse.olap/common/src/test/java/org/eclipse/daanse/olap/query/component/UtilTestCase.java

``

/**
 * Unit test for {@link mondrian.util.ArrayStack}.
 */
@Test
 void arrayStack() {
    final ArrayStack<String> stack = new ArrayStack<>();
    assertThat(stack.size()).isEqualTo(0);
    stack.add("a");
    assertThat(stack.size()).isEqualTo(1);
    assertThat(stack.peek()).isEqualTo("a");
    stack.push("b");
    assertThat(stack.size()).isEqualTo(2);
    assertThat(stack.peek()).isEqualTo("b");
    assertThat(stack.pop()).isEqualTo("b");
    assertThat(stack.size()).isEqualTo(1);
    stack.add(0, "z");
    assertThat(stack.peek()).isEqualTo("a");
    assertThat(stack.size()).isEqualTo(2);
    stack.push(null);
    assertThat(stack.size()).isEqualTo(3);
    assertThat(stack).isEqualTo(Arrays.asList("z", "a", null));
    String z = "";
    for (String s : stack) {
        z += s;
    }
    assertThat(z).isEqualTo("zanull");
    stack.clear();
    assertThatThrownBy(() -> stack.peek()).isInstanceOf(EmptyStackException.class);
    assertThatThrownBy(() -> stack.pop()).isInstanceOf(EmptyStackException.class);
}

then replace in all iml and remove old class and then run legacy
