Thanks, I saw that go by.

Equinox was one of the early adopters of parallel class loaders during its design and eventual inclusion in Java 7.  Long ago we stopped needing any such flags to prevent deadlock with our non-hierarchical class loaders.  This should have no impact for Eclipse projects that are based on Equinox.

Forwarding to equinox-dev as I think that is the part of the IDE that has class loaders. Jonah ~~~ Jonah Graham Kichwa Coders www. kichwacoders. com On Tue, 1 Nov 2022 at 13: 37, Ivar Grimstad <ivar. grimstad@ eclipse-foundation. org ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍ ‍

Hi all,

For your awareness, here is a change in the JDK that may impact some of our projects. I suspect it may be something to look into at least for the IDE, EclipseLink, GlassFish, others?
Not sure how to handle it, or even if the Arch Council is the right place.

Hi Ivar,

To prevent deadlocks, we're planning to remove from the JDK a legacy
parallel class loading workaround for custom class loaders not
registered as parallel capable (see JDK-8295848). We'd like to know if
Eclipse doesn't depend on that legacy workaround and understand if its
custom class loaders using non-hierarchical class delegation model are
parallel-capable.

[1] https://bugs.openjdk.org/browse/JDK-8295848

Thanks,
