Joshua McKenzie updated CASSANDRA-9902:
---------------------------------------
Attachment: Not_Dep.jpg
I don't think it's DEP - I installed a 32-bit JDK, disabled dep via bcdedit,
and reproduced the crash via the dtest (see attached image). Also,
VMAttach.java doesn't actually crash C* on my system when I run it (though I
had to add System.loadlibrary("attach") to get it to run properly).
I'm running Windows 10 on this dev box so that might be a confounding factor,
but I think the whole "disabled DEP w/32-bit app and it crashes" thing probably
rules that out. There's definitely *something* wrong though, that's for sure. :)
The crash from java.exe when loaded up in VS has Exception code 0xC0000005,
"The thread tried to read from or write to a virtual address for which it does
not have the appropriate access". I wonder if it might be worth it to try and
reproduce with OpenJDK - if it does, we can generate .pdb files for that in
visual studio and actually debug a lot closer to the metal.
Seems like a hell of a lot of effort to debug an http bridge JMX attacher
though, that's for sure. A cursory search doesn't show up much in the python
ecosystem other than Jython for connecting to JMX, so I'm not sure we have a
lot of alternative options for this or other approaches to help narrow down
debugging.
And here I thought I was giving you an easy win by kicking this ticket your
way. Sorry about that.
