GraalVM native image support

[smiera]

Hi,

Using GraalVM native image build can speedup almost any Java application and use less memory.

I try to build native image from project that use jnr-fuse and get errors at runtime

Caused by: com.oracle.svm.core.jdk.UnsupportedFeatureError: No classes have been predefined during the image build to load from bytecodes at runtime.
	at com.oracle.svm.core.util.VMError.unsupportedFeature(VMError.java:87)
	at com.oracle.svm.core.hub.PredefinedClassesSupport.throwNoBytecodeClasses(PredefinedClassesSupport.java:76)
	at com.oracle.svm.core.hub.PredefinedClassesSupport.loadClass(PredefinedClassesSupport.java:130)
	at java.lang.ClassLoader.defineClass(ClassLoader.java:263)
	at jnr.ffi.provider.jffi.AsmClassLoader.defineClass(AsmClassLoader.java:36)
	at jnr.ffi.provider.jffi.AsmStructByReferenceFromNativeConverter.newStructByReferenceClass(AsmStructByReferenceFromNativeConverter.java:170) 

How I understand, JNR create classes at runtime. And this is problem for native image.

So the question is: can you prepare library for native image build or pre-generate classes for GraalVM agentlib?
