UnsatisfiedLinkError on Ubuntu x64

[Arzk]

I'm trying to install MinimServer on my headless Ubuntu server running 12.04 x64, but I keep getting an error when running bin/startc:

Code:

java.lang.UnsatisfiedLinkError: /tmp/minim-native-7875338365460665013/libohNet.so: /tmp/minim-native-7875338365460665013/libohNet.so: failed to map segment from shared object: Operation not permitted

I'm using openjdk-7-jre-headless (java version "1.8.0_77"). I read from some old posts that libstdc++6 would be the fix for this error, but I already have the library installed. MinimServer version is 0.8.3f.
