Bug#898248: xz-java: FTBFS with Java 10 due to increased javadoc strictness

[Emmanuel Bourg]

Source: xz-java
Severity: serious
User: debian-java at lists.debian.org
Usertags: default-java10

xz-java fails to build with Java 10 because javadoc is unable
to find the package-list file from the JDK documentation at
the usual path:
