When I fixed: 7022998: JSR 292 recursive method handle calls inline themselves infinitely I noticed that bench_tak.rb is faster with MaxRecursiveInlineLevel=0 but I can't think of anything we could do about that. > > A related question: what would it take to get the hsdis plugin > included with openjdk proper all the time?

But if you have a working hsdis library just put it on you LD_LIBRARY_PATH.
