SUGGESTED FIX http://hg.openjdk.java.net/jdk7/hotspot-gc/hotspot/rev/c766bae6c14d

EVALUATION A too-strong assert, newly introduced in 6896603, which will need to be suitably repositioned. The assert, where currently positioned, is too strong in the case when we ask for an explicit gc from the gc locker and an incremental collection of the young generation fails due to a promotion failure.
27-10-2010
WORK AROUND A benign issue; the assert in question was much too strong. Not an issue for product builds. For debug builds, the following workaround is sufficient: -XX:SuppressErrorAt=<...> ... = defNewGeneration.cpp:827 or as appropriate.
