      Description

      Doing a stackdump while "maven-javadoc-plugin:3.0.1:jar (attach-javadoc)" shows thread spending a lot of time in UnixNativeDispatcher.getgrgid.

      This was not visible in java 8 and javadoc plugin version 2.4.

      Our previous build time has been increased from 5min to 3h 30min.

      Tested version Java 11 and 3.0.1 of maven-javadoc-plugin

      maven config:

       

      <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-javadoc-plugin</artifactId>
      <version>3.0.1</version>
      <executions>
        <execution>
          <id>attach-javadocs</id>
          <goals>
            <goal>jar</goal>
          </goals>
          <configuration>
            <failOnError>false</failOnError>
          </configuration>
          </execution>
        </executions>
      </plugin>
