Review Comment:
> I have experienced a lot of the following error cases when running jar on
JDK 8 that built with newer JDK with release 8
Using `-target` or `--release`?
Because that's exactly the kind of problem `--release` solves compared to
`-target`.
It's easy to reproduce the problem and verify the fix:
```bash
$ cat > NoSuchMethod.java <<EOF
import java.nio.ByteBuffer;
public class NoSuchMethod {
public static void main(String[] args) {
System.out.println(ByteBuffer.allocate(100).position(20).limit(62).remaining());
}
}
EOF
$ usr/lib/jvm/java-11-openjdk-amd64/bin/javac -Xlint:none -source 8 -target
8 NoSuchMethod.java \
&& /usr/lib/jvm/java-8-openjdk-amd64/bin/java NoSuchMethod
Exception in thread "main" java.lang.NoSuchMethodError:
java.nio.ByteBuffer.position(I)Ljava/nio/ByteBuffer;
at NoSuchMethod.main(NoSuchMethod.java:6)
$ /usr/lib/jvm/java-11-openjdk-amd64/bin/javac --release 8 NoSuchMethod.java
\
&& /usr/lib/jvm/java-8-openjdk-amd64/bin/java NoSuchMethod
