Ed,

I noticed today that if I put multiple -XX: VMARG options, only the first is accepted.
I agree that using a lot of -XX are not good practice for launching the Eclipse platform, but are curious if this is considered a bug?

I don't have access to Bugizzla due to posting rules sorry.

Note that you can arbitrarily split the overall argument string between the Option feature and the Value feature. The option part is used to do merging. So if you special -XX as the option and have two of them with different values they will merge into one. If you won't want them to merge, specify everything (the whole argument) as part of the Option with no Value. E.g., these three tasks will be merged into only two tasks:

<?xml version="1.0" encoding="UTF-8"?>
<xmi:XMI xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:setup="http://www.eclipse.org/oomph/setup/1.0">
  <setup:EclipseIniTask
      option="-XXabc"
      value="xyz"
      vm="true"/>
  <setup:EclipseIniTask
      option="-XXabc"
      value="def"
      vm="true"/>
  <setup:EclipseIniTask
      option="-XXfoo"
      value="xyz"
      vm="true"/>
</xmi:XMI>

So I think with this approach you can achieve what you need, i.e., multiple different -XX arguments.
