I actually think the problem in Peter's particular case is that the
"Eclipse IDE for Java Developers" package specifies
"-Dosgi.requiredJavaVersion=1.5" in its eclipse.ini
While I understand that Mylyn requires 1.5, I don't think anything else
that is "crucial" to the Java dev tools does, so it seems to me that
this is an unnnecessary restriction for that package (Mylyn is, IMO,
still an optional piece of functionality that should not prevent the
entire tool from loading).

I've opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=248976 about this.

If bug 174515 is all that happens when Eclipse tries to load in a JRE
that's insufficient for its plugins, then it does seem like it might be
worth making eclipse.ini less fussy - or telling users how to do
themselves it in the documentation.

Anyway, here's my bug:

Thanks everyone for your help,
Peter
