Macos Mac OS X包中的0方法返回值

我在玩——我的第一个SWT应用程序。 当我打包EclipseSWT表java应用程序MacOSX10.6.8时，方法返回值为0。如果我删除.app并执行应用程序可执行文件，它就可以正常工作。它在eclipse中运行良好。它在Windows7中运行良好。“调试”消息框始终包含正确的值。如果我硬编码表clientHeight、headerHeight和itemHeight，则返回值是正确的

private int adjustItemsNEEDED(Table tTable) {
    int itemsNeeded = 0;
    int clientHeight = tTable.getClientArea().height;
    int headerHeight = tTable.getHeaderHeight();
    int itemHeight = tTable.getItemHeight();

    if (itemHeight != 0) {
        itemsNeeded = (clientHeight - headerHeight) / itemHeight;
    } else {
        itemsNeeded = 0;
    }
    messageTextBoxTop.setText("height=" + clientHeight + " header=" + headerHeight + "                item=" + itemHeight + " needed=" + itemsNeeded);
    return itemsNeeded;
}

我的可执行文件：

#!/bin/sh
BASEDIR=`dirname $0`
exec java \
-d64 \
-XstartOnFirstThread \
-classpath $BASEDIR/org.eclipse.SWT.cocoa.macosx.x64/swt.jar:$BASEDIR \
-Djava.library.path=$BASEDIR/org.eclipse.SWT.cocoa.macosx.x64 \
