Regression comparing 2.5 and 2.5.1, NPE in CoberturaReportMojo
--------------------------------------------------------------
Key: MCOBERTURA-151
URL: https://jira.codehaus.org/browse/MCOBERTURA-151
Project: Maven 2.x Cobertura Plugin
Issue Type: Bug
Affects Versions: 2.5.1
Reporter: Rostislav Svoboda
Priority: Critical
CoberturaReportMojo in getAllChildren method throws NPE for version 2.5.1.
Version 2.5 works without NPE.
Aggregated report is generated by Maven plugin for Cobertura.
Tested on AS7 source codes (https://github.com/jbossas). No errors when using
version 2.5 [1] but NPE using 2.5.1 [2], see stacktrace.
There are different implementations of getAllChildren method for version 2.5
and 2.5.1 - see [3] and [4].
[1] mvn -e -Pcode-coverage -Dcobertura.aggregate=true

[2] mvn -e -Pcode-coverage -Dcobertura.aggregate=true
-Dversion.cobertura.plugin=2.5.1 clean cobertura:clean cobertura:cobertura
