eclipse NEON 不断卡住

Question

Eclipse Neon 启动后不到两分钟就不断卡住。没有显示错误消息或异常，工作台只是停止响应。 .log 文件中有无数异常，例如:

已报告有关 GTK3 的问题，但即使强制 GTK2，工作台也会继续卡住。这些是 eclipse.ini 文件的内容:

-startup
plugins/org.eclipse.equinox.launcher_1.3.200.v20160318-1642.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.gtk.linux.x86_64_1.1.400.v20160518-1444
-product
org.eclipse.epp.package.java.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
--launcher.defaultAction
openFile
--launcher.appendVmargs
--launcher.GTK_version
2
-vmargs
-Dosgi.requiredJavaVersion=1.8
-XX:+UseG1GC
-XX:+UseStringDeduplication
-Dosgi.requiredJavaVersion=1.8
-Xms256m
-Xmx1024m

是什么导致了这种行为？可以以某种方式修复它吗？请注意，我对 Eclipse Mars 或 Eclipse Luna 都没有此类问题。

当我删除 StatET plug-in 后，这些卡住问题就消失了。 。我在 StatET 邮件列表上发起了一次讨论，但没有结果(不幸的是，目前没有我可以指向的事件文件)。

本质上:这个插件不稳定，应该避免。
