RFR: 8003348: SA can not read core file on OS X

[Staffan Larsen]

Thanks for doing this Yumin!

I tried to apply you patch and run it, but I can't get SA to open a core file. You can see the exception I get below. Is there some kind of setup I need to do? This is against a jvmg build of Hotspot.

I also noticed that you forgot to update BugSpotAgent.java with the same changes as in HotspotAgent.java. This makes the jstack tool fail.

I will look at the changes more closely.

Thanks,
/Staffan



Opening core file, please wait...
