Expected & Actual behavior (期望与实际表现)

hugegraph-dist/src/assembly/static/bin/hugegraph-server.sh

if [[ $? -ne 0 || $JAVA_VERSION < $EXPECT_JDK_VERSION ]]; then
    echo "Please make sure that the JDK is installed and the version >= $EXPECT_JDK_VERSION" \
         >> ${OUTPUT}
    exit 1
fi

directly using < may cause problem。My default java 11 will exit at this. but java 11 is bigger than java 8.

I have encountered this problem before. I must start the project with java 1.8
