Netbeans cannot find java.lang no jdk9

Question

I am trying to install new Netbeans (8.1) on jdk 9. But netbeans cannot find java.lang. I checked the Java platform and saw the following:

the following elements were added as “platform sources”:

C:\Program Files\Java\jdk1.9.0\jrt-fs.jar
C:\Program Files\Java\jdk1.9.0\src.zip
C:\Program Files\Java\jdk1.9.0\javafx-src.zip

but I get this error and cannot make it work:

cannot access java.lang
  Fatal Error: Unable to find package java.lang in classpath or bootclasspath

Thank you in advance
