After updating java8 to java9, eclipse cannot start?

Question

I installed newly released jdk 9 and uninstalled all the old jdk 8 and jre 8.

I have this item in my win7 system Enviroment Variables: Variable name: JAVA_HOME, Variable value:C:\Program Files\Java\jdk-9, and %JAVA_HOME%\bin in Enviroment Variables PATH.

When I launch Eclipse which works normal yesterday with JDK8, I can see the start page then a pop up window which says:

AN error has occurred. See the log file D:\Tool\eclipse\Workspace\.metadata\.log.

Here's the content in aforementioned log file:

How to solve this problem? Thanks.

You'll need a newer version of Eclipse that supports Java 9. Or have both Java 8 and Java 9 installed, if you need Java 9 for other reasons, and [tell Eclipse to use the Java 8 installation](https://stackoverflow.com/q/6881622/5221149). — Andreas, Sep 27 '17 at 03:12
java.lang.ClassNotFoundException is a symptom of the new modular class libraries of Java 9. — nitind, Sep 27 '17 at 03:36

None of the currently released Eclipse versions work out-of-the-box with Java 9; those versions will come next month starting with Oxygen.1a. Follow these instructions to get the older version to work with Java 9: https://wiki.eclipse.org/Configure_Eclipse_for_Java_9#Configure_Eclipse_for_Java_9_modules , or go back to Java 8 for now. You can use the -vm command line switch to force Eclipse to use a particular JVM executable.

I went back to Java8, But still getting same issue. On terminal JAVA_HOME points to jdk8 and java -version gives java 1.8.xx but eclipse Oxygen still doesnt launch. Is eclipse not picking Java8 ? – user204069 Nov 09 '17 at 07:05
There's no guarantee that you're running into exactly the same problem. You should open a question with your details. – nitind Nov 09 '17 at 12:50
