Why does Jetbrains install its own JDK for use with its IDEs?

I was looking checking the version of my Rubymine recently and noticed that it seems to be using a JVM provided by Jetbrains. What is the purpose of this? Why not use a JDK installed by the user?

Solution

  • A couple of reasons.

    • It allows them to have the IDEs run in a known, tested environment.

    • It reduces the number of environments (versions) they have to verify.

    • It keeps problems in a user's JVM from causing problems in their IDEs.
