src/share/vm/gc/shared/collectorPolicy.cpp:
700           log_warning(gc, 
ergo)("GenCollectorPolicy::mem_allocate_work retries %d times \n\t"
701                                 " size=" SIZE_FORMAT " %s", 
try_count, size, is_tlab ? "(TLAB)" : "");

873       log_warning(gc, ergo)("satisfy_failed_metadata_allocation() 
retries %d times \n\t"
874                             " size=" SIZE_FORMAT, loop_count, 
word_size);

After UL we avoid having multi-line logging statements. So I suggest you 
either re-format these to only use a single line each.

Otherwise the change looks good.

Thanks,
Stefan
