publican-4.3.2-6.fc27 fails to build in F27 because tests fail like this:

t/200.XmlClean.t .............. ok
Making portrait pages on USletter paper (8.5inx11in)
/usr/bin/fop: JAVA_HOME is not set and default java installation was not found. JAVA_HOME for system applications can be set in java.conf in /etc/java
#   Failed test 'build a book'
#   at t/300.Builder.t line 32.
# 
# FOP error, PDF generation failed. Check log for details.
#  at t/300.Builder.t line 27.
# Looks like you failed 1 test of 5.
t/300.Builder.t ...............
