Question

运行Mac（OS X 10.8.1）。我们升级到最新的Java安全更新1.6.0_35-b10-428，从那时起，我们的主应用程序无法在Eclipse中启动。

启动Openfire 3.6.4时会抛出以下异常。几乎解析openfire.xml配置的地方是错误发生时：

 private void buildDoc(Reader in) throws IOException {
    try {
        SAXReader xmlReader = new SAXReader();
        xmlReader.setEncoding("UTF-8");
        document = xmlReader.read(in);
    }
    catch (Exception e) {
        Log.error("Error reading XML properties", e);
        System.out.println("NOOO");
        e.printStackTrace();
        throw new IOException(e.getMessage());
    }
    finally {
        if (in != null) {
            in.close();
        }
    }
}

抛出异常：

编辑：按照建议添加了Xss1m，但是当应用程序进一步发展时，我看到了同样的错误。这是我的创业公司：

这是我的创业公司args：

-DopenfireHome =“$ {workspace_loc：openfire} / target / openfire”-Djava.net.preferIPv4Stack = true -Xms32m -Xmx512m -Xss1m -XX：ThreadStackSize = 128 -XX：PermSize = 72m -XX：MaxPermSize = 96m -XX：+ PrintGCDetails -Xloggc：/tmp/gc.log -XX：+ HeapDumpOnOutOfMemoryError

EDIT2：

似乎以下修正工作：修改-Xss128k到-Xss1m并删除-XX：ThreadStackSize = 128

Answer 1

您是否尝试增加堆栈大小？您可以通过在启动JVM时指定-Xss1m来执行此操作。在示例中，JVM将为每个线程分配1兆字节的堆栈。注意不要使用太大的值，因为它将乘以应用程序中的线程数。

要在Eclipse中更改配置，请按照以下步骤操作（从here复制）。

打开应用程序的运行配置（运行/运行配置...，然后在'Java应用程序'中查找应用程序条目）。

参数选项卡有一个文本框Vm参数，输入-Xss1m（或最大堆栈大小的更大参数）。默认值为512 kByte。

编辑：

看起来这是一个常见问题。安全补丁可能引入了对链的另一个方法调用，并且以前适合堆栈的所有项目都不再适合。
