Stefan Birkner commented on SUREFIRE-649:
-----------------------------------------
The Bug happens inside of
org.codehaus.plexus.component.configurator.converters.AbstractConfigurationConverter.fromExpression(
PlexusConfiguration configuration, ExpressionEvaluator expressionEvaluator ).
Within this method the empty string is converted to null.
> Might be impossible to have empty strings in systemPropertyVariables element

> Key: SUREFIRE-649
> URL: http://jira.codehaus.org/browse/SUREFIRE-649
> Project: Maven Surefire
> Issue Type: Bug
> Components: Maven Surefire Plugin
> Affects Versions: 2.6
> Reporter: Laird Nelson
> Attachments: surefireEmptyStringIssue.tar.gz
>
>
> This stanza:
> <systemProperties>
> <property>
> <name>emptyProperty</name>
> <value></value>
> </property>
> </systemProperties>
> ...yields "" from System.getProperty("emptyProperty").
> This (supposedly better) stanza:
> <systemPropertyVariables>
> <emptyProperty></emptyProperty>
> </systemPropertyVariables>
> ...yields null from System.getProperty("emptyProperty").
> A test case is attached that demonstrates the issue.
