-----------------------------------------

Hi [~michael-o], the ASM 6.2 is released. However, I didn't find the right 
place update Maven Compiler Plugin (I checked 
https://github.com/apache/maven-compiler-plugin/blob/master/pom.xml). Could you 
help me to update this dependency?

My workaround is to override the version on my own project:

{code:title=pom.xml}
        <plugin>
          <artifactId>maven-compiler-plugin</artifactId>
          <version>3.7.0</version>
          <dependencies>
            <dependency>
              <groupId>org.ow2.asm</groupId>
              <artifactId>asm</artifactId>
              <version>6.2</version>
            </dependency>
          </dependencies>
        </plugin>
{code}
