This is the current state in Tycho 2.0.0-SNAPSHOT (or at least what's desired).

But all this only loosley relates to BundleRequiredExecutionEnvironment.

The relationship is when a bundle uses useJDK=BREE: the JRE that will be used for compilation will come from toolchain definition and may not be the one that's used for dependency resolution against the execution environment (specified via .target file or otherwise); and -unless I'm mistaken- the compile classpath is derived from the EE and not from the actually used JDK, so it's probable that by resolving classpath against a different JRE than the one used for compilation, there may be missing packages.
