nullpointerexception - Eclipse RCP 应用程序无法在 MacOS 上运行

问题描述

我们有一个在 Windows 上运行的旧 Eclipse RCP 应用程序（Luna Service Release 2 (4.4.2)），需要配置为在 MacOS 上运行

在为 MacOS 添加缺少的插件后，应用程序在尝试以调试模式运行应用程序时返回一堆 NullPointerException（附在下面）。此外，当我们构建目标并尝试从生成的源中打开它时，它会卡在您选择工作区的窗口中，并且您无法单击任何按钮或选择任何内容

设置：Java：1.8.0_301 Eclispe：4.4.2 Luna Service Release 2 MacOS：11.5.2 Big Sur

这是我调试应用程序后的最新堆栈跟踪：

解决方案

这看起来像 Eclipse 错误434393。

该错误在 Eclipse 4.5 中被标记为已修复，因此您至少需要迁移到该版本。

然而，旧版本的 Eclipse 在 macOS 11 上存在各种 UI 显示问题，因此如果您要更改版本，您应该迁移到当前的 Eclipse 4.20（即将成为 4.21）
