> _JAVA_OPTIONS interferes with javadoc version detection
> -------------------------------------------------------
>
> Key: MJAVADOC-435
> URL: https://issues.apache.org/jira/browse/MJAVADOC-435
> Project: Maven Javadoc Plugin (Moved to GitHub Issues)
> Issue Type: Bug
> Reporter: Tim Smith
> Assignee: Robert Scholte
> Priority: Major
> Fix For: 3.0.1
>
>
> Per MESOS-3482, `java` can print extra output to stderr at launch if the
> `_JAVA_OPTIONS` environment variable is set, like this:
> {noformat}
> tim@rocketman:temp$ _JAVA_OPTIONS=-Duser.home=/tmp java -version
> Picked up _JAVA_OPTIONS: -Duser.home=/tmp
> java version "1.8.0_45"
> Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
> Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)
> {noformat}
> This plugin attempts to parse stderr to learn the javadoc version and does
> not expect the additional output.
> The failure looks like:
> {noformat}

> problems for maven projects that use this plugin.
