Check, in LinuxNativeBridge.java: final String responseAddress = StringUtil.parseString( string, "from ", " "); final String ttlAsString = StringUtil.parseString( string, "ttl=", " "); On linux (tested on Debian Buster), the response may be: "From nnn.nnn.nnn.nnn icmp_seq=3 Destination Host Unreachable" so both responseAddress and ttlAsString are null. The following final int ttl = Integer.parseInt(ttlAsString); raises NumberFormatException; Same for rttAsString;
