Hi,

See https://wiki.eclipse.org/Tycho/Release_Notes/2.0#Target_platform_resolution_becoming_more_correct

Basically, the BREE is only used to set the source/compile level in the compiler and isn't used to set the target-platform/library level. For such package that have been removed from a java version to the other, you should make sure those packages are imported in MANIFEST.MF. Against Java 8, they'll resolve to the package in the execution environment; against Java 11, they'll resolve to the javax.xml bundles.
