The selected directory is not a valid home for JDK

Hi I have installed jdk 10 in ubuntu 16.0.4 using following commands.

sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install oracle-java10-installer

Below link I followed to install java.

After installation I am checked with following commands.

java -version

javac -version 

They are showing correct versions.

I tried the both options of installation but when I am giving jdk path form intellij I am getting 

"The selected directory is not a valid home for JDK'' error.

Please help since I am stuck here from last 3 days.
