The call to ClassLoaderDataGraph::clear_claimed_marks() during initial mark in g1CollectedHeap.cpp:4420 seems to be superfluous.
This work is already done during the start of the following concurrent phase (concurrentMarkThread.cpp:137), so there is the question why this work is done twice for no reason.
Investigate whether it is possible to remove this (sometimes time-consuming) call during initial mark, either completely or merging it with other phases iterating over all class loader datas.
