Wouldn't it be enough if we could convince eclipse to accept a
"hand-made jre"? I mean one where you can you explicitly set the
individual binaries that make up the tools that eclipse expects? Plus
convincing the built-in eclipse compiler to use a flat (non-jar/zip)
bootclasspath? (I believe ecj can use dirs already, but haven't

It feels like eclipse is just trying to be too clever in its "jre
detection". Maybe if the "JRE definitions" preference box had an
"override - I know what I am doing" box, so you could fill in the
individual parts that make up the "StandardVMType" thing.

If you take a quick look at
org/eclipse/jdt/internal/launching/ it looks like
this class just needs a set of setters and a way to override that auto
detection. Or maybe we need a new subclass of AbstractVMType that
creates an IVMInstall just based on user defined locations that can be
plugged into the standard JRE preferences dialog as override to the
autodetecting StandardVMType?
