Using a default eclipse install, pointing to a default EAP 6.1 (and probably any other server) it chooses:

"Default JRE for JavaSE-1.6" as its JRE.

Even though I have an Java SE installed as the default runtime for this JRE.

Then the wizard tells me:

"This runtime type requries a JDK for launching a server. We cannot guarantee the default virtual machine for this execution environment is a JDK".

and its cut off in the middle of the last line.

A) why not choose the JDK execution environment when one is there ?

B) since the execution environment actually points to a JDK the warning is not correct

C) The text is hard to grok.

• the title says server but text says runtime
• the warning shows up for the default behavior
• use "a server" when it is a specific one

suggestion for simplification:

"The server runtime requires a JDK to launch. 'Default JRE for JavaSE-1.6' does not look like a JDK"

...actually - this is just as horrible.

If we cannot detect the various execution environments are a JDK reliably we shouldn't warn at this time. It is confusing.

How come Java 7 execution environment is detectable as a JDK but the Default JRE is not ?
