Joshua McKenzie commented on CASSANDRA-9902:
--------------------------------------------
bq. Did you add tools.jar to the classpath during compilation and execution?
I did - it gave me the following w/out the loadlibrary / java.library.path:
{noformat}
java.util.ServiceConfigurationError: com.sun.tools.attach.spi.AttachProvider:
Provider sun.tools.attach.WindowsAttachProvider could not be instantiated
This error
com.sun.tools.attach.AttachNotSupportedException: no providers installed
{noformat}
bq. Did it print only "success!" without any errors, successfully attaching to
the JVM and exiting?
It did. Updated to 8_u51 (to fix the ProgramData hard links) and it's still
succeeding.
bq. You also need to run C* process and VMAttach both on an administrator shell
Yep - doing so (more from dumb luck from bcdedit / wmic changes and
confirmation than anything), but confirmed again - and it's definitely working.
Updated to 8_u51 and it's still succeeding.
bq. I wonder if there could also be some crazy conflict between JDK7 and JDK8,
even though I purged all JVMs from my system with JavaRa, but maybe JDK8 leaves
some uncleaned garbage. Would be nice to try reproducing on a clean system with
only JDK7 ever installed.
I have a version of 7 on here and 8 both, so if it's that it might be a vestige
of the environment hanging around on your side?
If I come up with anything other than JVM debugging as an idea I'll kick it
your way.
