  <p>but when i check the protopayload in the logger it is always <strong>1.9.71</strong> and java version is also older <strong>1.8.0_181-google-v7</strong>(July 2018)</p>
  <p>Im curious to know is there an option to update latest openjdk java8 version in standard environment.</p>
  <p>Thanks,</p>
