Deciding on the documentation text requires more discussion. Moving to 4.8RC3

Action item after further discussion today
-------------------------------------------
It was good if PDE also shows default({0}) as the text ( that would show as default ( javaw)  if default is not overridden ) just like java application ( jre tab - clicking on alternate JRE).

Opened Bug 535122 based on multiple discussions. This bug will just track the documentation.

Comment 3 Sarika Sinha 2018-06-01 00:20:43 EDT

jdt.debug.ui defines -
<extension
         point="org.eclipse.jdt.debug.ui.vmInstallTypePage">
      <vmInstallTypePage
            vmInstallTypeID="org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType"
            class="org.eclipse.jdt.internal.debug.ui.jres.StandardVMCommandTab"
            id="org.eclipse.jdt.debug.ui.StandardVMCommandTab">
      </vmInstallTypePage>
 
   </extension>

org.eclipse.jdt.internal.debug.ui.jres.StandardVMCommandTab.getDefaultCommand() defines the default command which is used to append to "Default" in the Java executable section of JRE tab.

Currently Alternate command in Java executable section is defaulted to same as getDefaultCommand() if not provided already but if it is same as getDefaultCommand() eventually while saving, then it is saved as Default radio button selection.

So, how does this related to the PDE Main tab? Not clear to me after your comment.

PDE does not seem to use org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType"

Yes, as PDE does not use this type or the StandardVMCommandTab, it can use the same attribute to append to default.

String javaCommand = config.getAttribute(IJavaLaunchConfigurationConstants.ATTR_JAVA_COMMAND, "javaw");

Right and this is in org.eclipse.pde.internal.ui.launcher.JREBlock where we also have the button with the label
==> So, it is super easy to show the default value in the UI as suggested in 535122 1). We should make this simple change for RC4.

For the documentation we can just say that the default can vary but is shown im the UI.
