Good timing ... I've just finished checking with the Eclipse base, and
discussed (via email) with rest of WTP Architecture group.
In short, no, we are still building and testing at 1.4.2_08 level
libraries -- and, I recommend we continue to -- unless specific project
needs dictate otherwise, and even in those cases, these rules would be
"relaxed" on a plugin by plugin basis.
For committers, this means in your development environment, leave the
compiler compliance level set to 1.4, which actually means that .class
files are compatible with 1.2 and the source compatible with 1.3
The reason for this recommendation to WTP is that there are many
platforms and JRE's that adopters build on (with all or some with
subsets of WTP), and many still at 1.4 (or lower!?) level, so we
can not yet "pre-req" Java 5.0 for all WTP users or adopters, and we
want to match what the Eclipse base does.
There may be some exceptions, and this is where the real complications
will arise. Some functions that are being considered for WTP 1.5 (such
as JSR 188) will require
Java 5 to work, so, we must insure all function and plugins that require
Java 5.0, have an "execution context" specified, so if running in 1.4,
they will not be activated, and that
function simply not available (gracefully). So ... anyone contributing
such function also needs to contribute to our build process, to use
correct compiler settings for Java 5.0 pre-req plugins, plus improve the
JUnit test process so correct JRE is used when testing Java 5.0 function.
I'm sure this is disappointing to many who love using the 5.0 language
constructs, but, unless there is a "project need", then we can not yet
use these for our programming convenience or productivity.
Naturally, if any one in community (including committers! :) have any
concerns or questions about this restriction, please discuss.

[wtp-dev] Compiler level on the 1.5 stream
Is the 1.5 code stream being built with a Java 5.0 compiler? If it is,
are 5.0 language constructs allowed in the 1.5 code stream?
