Description

The test cases testSimpleGraphPng and testSimpleGraphSvg under TestGraphGenerator.java fail with java.lang.NullPointerException.
Maven command used for testSimpleGraphPng is mvn -Dtest=TestGraphGenerator#testSimpleGraphPng test.

Have observed that the test cases use the values from the enum OutputFormat which contains 3 constants : PNG, DOT & SVG
The test cases using OutputFormat.DOT have passed whereas the once which have used the other two constants i.e PNG and SVG , fail on ppc64le arch.
