Re: [equinox-dev] Latest release of org.eclipse.equinox.region bundle
I looked at this in some more detail. It does appear there is an issue (in the latest version also) where uninstalled bundles may cause this NPE if they are in the 'removal pending' state when another bundle is installed with the same symbolic name. Could you open a bug on this and give some details on what scenario caused the NPE? I don't recall if the specification requires removal pending bundles to be considered as collisions when new bundles are being installed. Looking at Equinox it appears we consider removal pending bundles as collision candidates. I'm assuming the felix framework does the same.
