From looking at http://rhq-project.org/display/RHQ/API+Changes+Between+JOPR+2.3.1+And+RHQ+3.0.0 There seem to be a number of candidates for removal: * AdvisoryManagerRemote * EntitlementStuffManagerRemote * PerspectiveManagerRemote * SavedSearchManager Because these features are unused in the JON2.4 release or will go through substantial change in the next release.
These and more were removed. SavedSearchManager was maintained after a discussion where it was decided the API is in decent shape. Not all saved search options may be initially supported but the API is good.
Note, much of this work was performed earlier, here: https://bugzilla.redhat.com/show_bug.cgi?id=580254
