as discussed on IRC GNU Classpath I introduced a system property named gnu.classpath.boot.library.path which contains a path of directories where Classpath's native libraries are located.
It is optional for a runtime to support. Actually it depends on the VM's ability to run a non-default Classpath installation. By default the property is not set and so it won't cause any trouble. The proprietary VMs have a similar property but that is not a matter for us because the feature is not specified.
On IRC I was told that it is the VM's task to find a native library. However by looking in java.lang.Runtime I found a piece of code that iterates through a String array of directory names. On each iteration it prepends a directory name to a library name and tries to load it. This array is created in the constructor of Runtime by evaluating the java.library.path property.
This algorithm is only used if a VM was not able to load a native library via VMRuntime.nativeLoad().
That means we support finding a native library through the VM itself and through Classpath. For JamVM the latter one is used.
