I recently updated PhpStorm to latest version 2017.1 and I get following message while starting PhpStorm
IDE's Java runtime (1.8u111) is outdated - this may cause stability issues. Please update to 1.8.0u112 or newer
But If you don't have the latest JDK, download it from: Download latest JAVA JDK here
And then select the "IDE BOOT JDK" like Tall Liou told.
