[eclipse-pmc] Proposal to move CDS Equinox adaptor (OpenJ9 class sharing

["Thomas Watson" <tjwatson@xxxxxxxxxx>]

 

Hello,

 

The OpenJ9 project will be the initial host project where the IBM Java team is contributing something called the CDS Equinox adaptor (see https://github.com/eclipse/openj9/pull/2167).  In short, it provides a hook into the Equinox class loader to allow the Equinox class loaders to take advantage of the shared classes functionality provided by OpenJ9.  This provides significant performance improvements when launching with OpenJ9 and the JVM shared classes cache is enabled.

 

I have discussed with the Java team and we have agreed that this code should move to Equinox.  My plan is to place the shared class support directly into the Equinox framework to make it as easy as possible to realize the performance improvements when launching with OpenJ9.  Any objections or concerns with me initiating a move review once this code is in the OpenJ9 project?
