Seg fault in bindJavaMethodsToCFunctions ? #573
Description
I developed an app using Bridj with WebSphere Liberty, and it seemed to work fine on my dev machine, but when I tried to deploy it on another Ubuntu machine, I get this error during initialization time:

---------------------------------------
The JVM on the deploy machine is newer than on my dev machine, but I didn't think that would matter. Any insight as to what would cause a segmentation error in bindJavaMethodsToCFunctions?
This is from the deploy machine: (where it fails)
Launching defaultServer (WebSphere Application Server 8.5.5.3/wlp-1.0.6.cl50320140731-0257) on IBM J9 VM,
And on my dev machine, where it works:
Launching defaultServer (WebSphere Application Server 8.5.5.2/wlp-1.0.5.cl50220140403-1858) on OpenJDK 64-Bit Server VM, version 1.7.0_85-b01 (en_US)
