+Summary: marshaling conversion 16 not implemented
+
+Following code compiles with mcs 0.16 but is not accepted by mono 0.16.
+Instead of running silently following error messages are generated:
+
+** (./HelloJava.exe:4507): WARNING **: marshaling conversion 16 not implemented
+
+** ERROR **: file marshal.c: line 624 (emit_ptr_to_str_conv): should not be
+reached
+aborting...
+./HelloJava: line 12:  4507 Trace/Breakpoint ausgelöst

+$0):${JAVA_LIBDIR}:${JVM_LIBDIR}${LD_LIBRARY_PATH:+:}${LD_LIBRARY_PATH}"
+MONO_PATH="${MONO_LIBDIR}${MONO_PATH:+:}${MONO_PATH}" mono "$0.exe" "$@"
+
+Problem appears to be that marshaling from JavaVMOption[] to
+UnmanagedType.LPArray doesn't work.
