Appears that rrd4j always tries to look for a font in the static initialization of RrdGraphConstants: https://github.com/rrd4j/rrd4j/blob/master/src/main/java/org/rrd4j/graph/RrdGraphConstants.java#L297 <https://github.com/rrd4j/rrd4j/blob/master/src/main/java/org/rrd4j/graph/RrdGraphConstants.java#L297> It is looking for DejaVuSansMono.ttf.
The MetricsHistoryIntegrationTest attempts a «get Grahp» in line 174, which then instantiates RrdGraphDef. Should probably factor out the graph test as a separate test, which is only run on systems with fonts installed.
