Eclipse Equinox 启动时出现 ClassCastException

Eclipse Equinox 启动时出现 ClassCastException

我已经在 Google 上搜索了大约 2 个小时，找不到任何其他人遇到此问题。每次启动 Eclipse 时似乎都会发生这种情况，这会导致 IDE 完全无法使用。我尝试过切换工作区，但没有任何变化。

我正在使用 Eclipse for Java EE 版本 4.4.1。

Java 版本：

java version "1.7.0_72"
Java(TM) SE Runtime Environment (build 1.7.0_72-b14)
Java HotSpot(TM) 64-Bit Server VM (build 24.72-b04, mixed mode)

名称：

Linux USERNAME 3.13.0-43-generic #72-Ubuntu SMP Mon Dec 8 19:35:06 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

已知的 Eclipse 错误，将在 Eclipse Luna SR2 (4.4.2) 中修复，根据https://www.eclipse.org/eclipse/development/plans/freeze_plan_4_4_2.php将于 2 月底发布（从今天起 1 个月后）。

注意https://bugs.eclipse.org/bugs/show_bug.cgi?id=445122，也给出https://stackoverflow.com/questions/26279570/getting-rid-of-org-eclipse-osgi-internal-framework-equinoxconfiguration1-that-c- 将其添加到 INI，对我有用：

-Dosgi.configuration.area.default=null
-Dosgi.user.area.default=null
