   I try `java -version` in my laptop, the result is 
   
   ```
   openjdk version "1.8.0_292"
   OpenJDK Runtime Environment Corretto-8.292.10.1 (build 1.8.0_292-b10)
   OpenJDK 64-Bit Server VM Corretto-8.292.10.1 (build 25.292-b10, mixed mode)
   ```
   
   So the result of `java -version 2>&1 | sed '1!d' | sed -e 's/"//g' | awk '{print $3}'` is: `1.8.0_292`
   
   I think the problem is in the first line `Picked up JAVA_TOOL_OPTIONS: -Djava.net.preferIPv4Stack=true`
   
   Is there any way to find the java version line and awk it?
