[jira] [Created] (MJAVADOC-435) _JAVA_OPTIONS interferes with
javadoc version detection
Tim Smith created MJAVADOC-435:
----------------------------------
Summary: _JAVA_OPTIONS interferes with javadoc version detection
Key: MJAVADOC-435
URL: https://issues.apache.org/jira/browse/MJAVADOC-435
Project: Maven Javadoc Plugin
Issue Type: Bug
Reporter: Tim Smith
Per MESOS-3482, `java` can print extra output to stderr on at launch if the `_JAVA_OPTIONS` environment variable is set, like this:
```
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)
```
This plugin attempts to parse stderr to learn the javadoc version and does not expect the additional output.
The failure looks like:
```

```
I think this should work even in the presence of _JAVA_OPTIONS.
Homebrew is considering setting this variable widely (tracking at https://github.com/Homebrew/homebrew/pull/44567) which would cause build problems for maven projects that use this plugin.
