yes and you should also be sure when
messing with the BundleRequiredExecutionEnvironment in PDE tthat you click
on the Update classpath link as that is what causes the project's compiler
compliance levels etc to be set at the JDT layer.

Getting a perfect match for a JRE can
be a battle.  For example, Foundation 1.1 is a subset of J2SE 1.4
so even if you have a 1.4 around, you can still end up in hot water at
runtime.  You can get Foundation 1.1 JREs from IBM 
        http://wiki.eclipse.org/J9
but until now adding such a JRE to the
list of installed JREs did not work well (or you had to go get some additional
support that worked in some situations).  Darin and the debug guys
have been busily working away on support for using .ee files to "install"
JREs.  Using this mechanism you can describe and install just about
any JRE.  Check out 
        https://bugs.eclipse.org/bugs/show_bug.cgi?id=181026

There are likely a few kinks right now
but we'll definitely have an .ee file for Foundation 1.1 available soon
(if not already).  this way we will get the right compliance levels
and the exact class libs.  So we won't have any excuses...

ECJ will not flag class usage issues (it does for generics,
but that's a syntax issue, per se). "Perfect match" for EEs are
the only way to prevent yourself from using the wrong classes, I believe.

Hi, Tim, 

The faux pas was mine, Susan reported it earlier, and Pascal delivered
the fix around noon today.  An interesting point was that the compiler
compliance level for the project was 1.4, but the issue was not flagged.

Sorry for the problem

Subject	[equinox-dev] [Prov] Build errors against CDC-1.1/Foundation-1.1

Hi,

I am running into some build errors with a few projects that appear to
be due to dependencies on calls only available in Java 1.5.  The execution
environment is listed as CDC-1.1/Foundation-1.1 which is linking against
1.4 on my system.  One of the offending classes is LocalMetadataRepository
with a reference to getCanonicalName().

Has anyone else seen this issue?  (This is building on an OS X system
with 1.4, 1.5 and 1.6 installed). 

Cheers,
Tim_______________________________________________
