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>
