Not that i am aware off, but have not looked too closely. There are a bunch of profilers available, i dunno if it is possible to plug in additional ones separate from JMH itself:

$ java -jar target/microbenchmarks.jar -lprof
Supported profilers:
                  gc: GC profiling via standard MBeans
                comp: JIT compiler profiling via standard MBeans
                  cl: Classloader profiling via standard MBeans
               hs_rt: HotSpot (tm) runtime profiling via implementation-specific MBeans
               hs_cl: HotSpot (tm) classloader profiling via implementation-specific MBeans
             hs_comp: HotSpot (tm) JIT compiler profiling via implementation-specific MBeans
               hs_gc: HotSpot (tm) memory manager (GC) profiling via implementation-specific MBeans
              hs_thr: HotSpot (tm) threading subsystem via implementation-specific MBeans
               stack: Simple and naive Java stack profiler
