Eclipse background Hint "computing additional Info" workaround

Workaround:

1. Locate the Src.zip file in your JDK installation directory;

2. Open the Eclipse:window menu->preference->java->installed JREs;

3. Select the JRE you are using in the list, and then edit;

4. Select Rt.jar, then click on the "Source Attachment" button, select "External file" after the popup dialog, and then Associate the Src.zip file in your JDK installation directory with the Rt.jar;

Computing Additional info will not appear again, and when you select the native class or method of the JDK in your code, pressing F3 also you can find the source code corresponding to Java.

The third-party JRE also resolves this.
