Re: [wtp-releng] 2.0M3 now must run under JDK5

[David M Williams <david_williams@xxxxxxxxxx>]

Yes, sorry if that was not announced
well enough, but when we moved to EMF M3, that nailed the runtime environment
to Java 5. 

This has always been our planned runtime
for WTP 2.0. But ... if that's an issue, better speak up quick! 

And, recall, this doesn't mean all plugins
can "willy nilly" use Java 5 features. In general, each individual

plugin should specify its Execution
Environment to the least possible runtime and only increase it if there's
a 
good reason to. (Similar to the principle
that no plugin should add a "requires bundle" unless there is
a good reason to). 

I'll be writing up some guidelines this
week for further technical information and policies for discussion. 

If any questions, please ask. 

Thanks for asking this one! 

P.S. technically our build environment
is only set up for Java 1.4 and Java 5 right now, but we can go lower later,

if anyone has some plugin they think
might be (re)used in a more constrained environment. 
(such as a mobile device, or light client).


P.S.S. Our JUnit tests are currently
using Java 5 for all the tests, but eventually we'll make that 
more specific to be what the tests really
require (some only require 1.4).

Subject	[wtp-releng] 2.0M3 now must run under JDK5

Sorry if this was announced and I just missed it,
but is it the case 
that 2.0M3 and forward must be run under JDK1.5?  When I try to run
under 1.4 I get the following in core EMF plugins:

Missing Constraint: Bundle-RequiredExecutionEnvironment: J2SE-1.5

Which causes its bundles not to load and that cascades across pretty 
much all WTP dependencies.
