Folks,
The only WTP plugin that I found that references
org.eclipse.equinox.common is org.eclipse.jpt.jpa.db.ui, and its BREE is
already at Java 8. However, there are a lot of other references to
org.eclipse.equinox.* bundles, so other plugins may need to update their
BREE (due to indirect references). If something breaks during the build,
WTP Releng will work to get it fixed... but these issues may not show up
until runtime. As such, I wanted the WTP community to be aware (and wary)
of this change.
FWIW,

Subject: [cross-project-issues-dev] BREE change to Java 8 on some core
plugins
Sent by: [email protected]
Hi,
With https://bugs.eclipse.org/bugs/show_bug.cgi?id=509234,
org.eclipse.core.runtime.ListenerList now overrides the default method
Iterable.spliterator() and provides stream() and parallelStream() methods.
Thus it exposes Java 8 types.
If you use the ListenerList class and compile against
org.eclipse.equinox.common within the [3.9,4.0) range, this change may
force you to update your BREE to Java 8 as well (like we had to do for
bundles org.eclipse.equinox.preferences, org.eclipse.core.jobs and
org.eclipse.core runtime).
Changing BREE is not required if you use ListenerList and still build
against older compatible version of org.eclipse.equinox.common (i.e. within
[3.0, 3.9) range). As many of us are compiling against latest versions of
bundles, think of it if you see compile errors like the following "The type
java.util.stream.Stream cannot be resolved. It is indirectly referenced
from required .class files".
Note that any previously compiled bundle depending on
org.eclipse.equinox.common within the [3.0,4.0) range will continue to work
as before.
Cheers,
