Build problems on Solaris 10 sparc
Just wanted to give everyone a heads-up. Starting with build 56, anyone who builds the server VM on older or unpatched versions of Solaris 10 may come up against a build error due to a bug in dtrace. If it happens a pretty detailed explanation should be displayed in the build output, but the long and short of it is that you'll need to either disable dtrace probes in that build by setting the environment variable HOTSPOT_DISABLE_DTRACE_PROBES, or make sure to use an updated or patched OS. I believe Solaris 10 update 1, build 15 and later will work, but if you have an earlier one, try to apply these patches: 118822-19 and 118844-19.
