- Thread-topic: [equinox-dev] Untangling standard and J9 CachingService bundles
Thank you for your help. Now I can build Equinox Aspects again. Yet I am still wondering if I like this design :-)
Yes, I will enter a bug report. And try to assign it. It's time to get familiar with committer tasks.

Betreff: Re: [equinox-dev] Untangling standard and J9 CachingService bundles
to let you setup and even build equinox aspects including the J9 caching
service you can import the project "build.ibm.oti". This mocks all the
shared classes API that is used for your workspace.
And the dependency on J9 in the standard caching feature is optional, I
think, so you don't need a J9 for running equinox aspects with the
standard caching service.
I agree to your comment with regards to the dynamics of the caching
services. Would you enter a bug report for this?
