jinfo causing segmentation fault on a 64 bit JVM

On a machine, I have jinfo resolving to:

/usr/bin/jinfo

When I run it against a 64bit JVM, I get:

jinfo -sysprops ${pid}

Attaching to process ID 26267, please wait...

The problem evidently is that THAT jinfo is a 32 bit version, and I should rather use /usr/lib/jvm/java-1.6.0-sun-1.6.0.81.x86_64/bin/jinfo
