Gili created MNG-5248:
-------------------------
Summary: NPE at EnvironmentUtils.toStrings()
Key: MNG-5248
URL: https://jira.codehaus.org/browse/MNG-5248
Project: Maven 2 & 3
Issue Type: Bug
Components: Plugin API
Affects Versions: 3.0.4
Environment: Ubuntu 10.04
Reporter: Gili
ProcessBuilder.environment() may contain keys with a null value. In my case
"INSIDE_NAUTILUS_PYTHON=" was defined. If maven-exec-plugin is invoked with the
same environment variables, the following exception is thrown:
{code}
java.lang.NullPointerException
at
org.apache.commons.exec.environment.EnvironmentUtils.toStrings(EnvironmentUtils.java:66)

org.apache.commons.exec.launcher.Java13CommandLauncher.exec(Java13CommandLauncher.java:56)

org.apache.commons.exec.DefaultExecutor.launch(DefaultExecutor.java:254)

at org.codehaus.mojo.exec.ExecMojo.executeCommandLine(ExecMojo.java:610)
at org.codehaus.mojo.exec.ExecMojo.execute(ExecMojo.java:352)
{code}
Expected behavior: EnvironmentUtils.toStrings() should be able to handle the
Map returned by ProcessBuilder with the same interpretation as it treats null
keys and values.
