Disabling OpenJDK related warning during Idea-10 startup.

Hi,

I am getting the following warning when openjdk is used as IDEA_JDK. And it asks for confirmation. Is there a way to disable this warning?

Thx,
Chandra

Here is the warning:

WARNING: You are launching IDE using OpenJDK Java runtime

THIS IS STRICTLY UNSUPPORTED DUE TO KNOWN PERFORMANCE AND GRAPHICS PROBLEMS

NOTE: If you have both Sun JDK and OpenJDK installed
please validate either IDEA_JDK or JDK_HOME environment variable points to valid Sun JDK installation

Hi chandra,

Do you get that warning with 10.0.x or with 10.5.x version of IJ?

Please submit corresponding bug report as v. 10.5 is assumed to provide support for the open jdk

one question:
Does this mean performance in SunJDK vs. OpenJDK is no longer an issue wrt Intellij?

Sun/Oracle JDK and Open JDK provide two different java runtime implementations. What performance aspect specific to IJ do you mention within them?

Mostly rendering related performance.
OpenJDK has few rendering issues compared to SunJDK. We used to specify pmoffscreen=false - which improves rendering with OpenJDK.

Sorry, don't have information about Open JRE vs Oracle JRE performance. We use Oracle JRE v.6 here internally.

Btw, pmoffscreen should affect only Unix environments without DGA support.
