Bug#875360: FTBFS with Java 9: ant can't find tool(?)

[Chris West]

Source: emma-coverage
Version: 2.0.5312+dfsg
Severity: normal
User: debian-java at lists.debian.org
Usertags: default-java9

This package fails to build with default-jdk pointing to openjdk-9-jdk.
Please fix it, so that we can start the transition to Java 9.
The wiki has some common problems and their solutions:

ant can't seem to load a tool, no idea what's going on here.
I don't expect this to be the only problem with Emma.

Build log:

-timestamp.1:
