> Cordova outputs "Picked up _JAVA_OPTIONS" in stderr
> ---------------------------------------------------
>
> Key: CB-9971
> URL: https://issues.apache.org/jira/browse/CB-9971
> Project: Apache Cordova
> Issue Type: Bug
> Components: Android
> Affects Versions: 5.0.0
> Environment: Windows, Tools for Apache Cordova in Visual Studio
> Cordova 5.4.0
> Reporter: Michael Braude
> Assignee: Vladimir Kotikov
> Priority: Critical
> Labels: easyfix, windows,
> Original Estimate: 2h
> Remaining Estimate: 2h
>
> Starting with version 5.4.0, Cordova now outputs "Picked up _JAVA_OPTIONS:
> -Xmx512M" to stderr. This breaks clients such as Visual Studio because we
> interpret messages in stderr to be errors, and this is not an error. So the
> result is that we show deploy failures to the dev when there are no errors.
> See this for customer impact:
> http://stackoverflow.com/questions/33603167/vs2015-build-with-cordova-cli5-4-0-shows-deployment-errors
> We can work around this in Visual Studio by using special casing, but Cordova
> needs to output this in stdout like it did in previous versions
