我想安装 Eclipse 2019-12，但是一旦我想打开安装程序，我就会收到错误消息。它说：
Internal error:
java.lang.ExceptionInInitializerError
当我点击details它时说：

当我点击update它时说：
This is an emergency update. Continue?
To lower the risks of problems duringthis update it will be implied thta you accept new licenses or unsigned content.
我之前已经安装了 Java JDK 15.0.2。
我怎样才能使这个 Eclipse 安装工作？
提前谢谢你。
