java - STS工具套件一直挂着

Question

Windows 10 中全新安装的 STS 版本 4.0.1.RELEASE(内部版本 201810300749)一直挂起。它总是在保存和内容辅助激活等方面挂起几秒钟。每隔几个小时左右，它就会完全卡在必须被杀死的地方。

多个作业和项目的所有 STS 安装都发生了这种情况，从具有 32 GB RAM 的核心 i7 到具有 16GB RAM 的 i5(几乎无法使用)。

我在ini文件中增加了内存。除了 m2e-wtp (Maven Integration for WTP) 之外，我也没有安装任何插件。

除了使用 Eclipse 之外，我们确实需要另一种选择。 Eclipse 4.5版本之后变得很慢。

以下是挂起时的堆栈转储。主线程卡在 FileOutputStream 写入调用上。
