@imbajin

fixed #1957

  1. use a better way to get the java version
  2. don't use float in shell directly (refer https://github.com/koalaman/shellcheck/wiki/SC2072)

  3. we shall use shell-check plugin to avoid these problems (improvement)

it's not easy to handle 1.7.xxx_xxx & 10.xx.xxx or 11.03.233

One way is we truncate the num before the 2nd . & trans it to int number (avoid using float)

  • 1.7.xxx_xxx --> 1.7 --> 7
  • 1.8.xxx_xxx --> 1.8 --> 8
  • 11.1.233 --> 11.1 --> 11

try this command: (check the logic)

java -version 2>&1 | head -1 | cut -d'"' -f2 | sed 's/^1\.//' | cut -d'.' -f1, it replace 1.7.xxx --> 7.xxx so that we could cut the first num to compare directly
