When validating plugin set for an Eclipse Runtime I get a
Missing-Constraint Bundle-RequiredExecutionEnvironment: JavaSE-1.6
problem. Is this constraint really neccessary? Hoping not as OS X
doesn't have 1.6..

What kind of issues might this cause on runtime side?

There are two jdt plugins that requires 1.6 in order to work.
compiler.tool and compiler.apt. They add the jsr199 (compiler API) and
the jsr269 (APT6 support) to the batch compiler.
If you don't have a 1.6 VM, then you don't get this support. You might
not care about it since these are 1.6 features.

Which bundles are reporting that? If it is the JDT "apt" and
"comiler.tool" stuff then it is OK to remove those from your runtime
config - they are only there to support 1.6-specific features.
See http://dev.eclipse.org/newslists/news.eclipse.tools.jdt/msg2 1421.html

The 1.6-specific features that those bundles provide just won't be
available.

Hope this helps,
Eric

It does, thx Eric! They were added when I selected required plugins,
assuming from some other part of jdt, and while apt seemed optional,
compiler.tool sounded important. :)
