This looks like a known problem with hsdis: the hotspot-disassembler interface had changed a little, 
so newer JDKs could not find the entry point in older hsdis libraries. You are looking for this symbol:

$ objdump -t /usr/lib/hsdis-amd64.so | grep decode_instructions_virtual
0000000000069d14 g     F .text	000000000000086c              decode_instructions_virtual

Try to either recompile hsdis from modern JDK source, or try a binary library from here:
