Re: [wtp-dev] Compiler level on the 1.5 stream

[David M Williams <david_williams@xxxxxxxxxx>]

Yes, we do need to update the one at

http://www.eclipse.org/webtools/development/eclipse_WTP_project_plan_1_0.html

As far as I know, the plaftorms will
be the same as for 1.0, but we will actively support RUNNING on Java 5.

[the original question and this thread
is only about what we compile our own code with]. 
And .. we need to add more 1.5 tests
to some of our automated tests ... just to be sure. 
And, as before, we'll have the caveat
of
"Although untested, Eclipse WTP should work fine
on other OSes that support the same window system. See also ....[base
plan]"

If any adopters have any other specific
platform needs, be sure to open feature requests, 
and/or let WTP "requirements and
planning group" know about it. 

Thanks,

David,

Do you have supported platform/jre matrix for WTP 1.5? I assume it is 
different from 
http://www.eclipse.org/eclipse/development/eclipse_project_plan_3_2.html#TargetOperatingEnvironments,
right?
