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?

Re: Disabling OpenJDK related warning during Idea-10 startup.

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

Re: Disabling OpenJDK related warning during Idea-10 startup.

one question:

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

Re: Disabling OpenJDK related warning during Idea-10 startup.

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

Re: Disabling OpenJDK related warning during Idea-10 startup.

Mostly rendering related performance.

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

Re: Disabling OpenJDK related warning during Idea-10 startup.

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.
