---------------------------------
Summary: Tests can be made more robust to pass in Java 8
Key: MAHOUT-1610
URL: https://issues.apache.org/jira/browse/MAHOUT-1610
Project: Mahout
Issue Type: Bug
Components: Integration
Affects Versions: 0.9
Environment: Java 1.8.0_11 OS X 10.9.4
Reporter: Sean Owen
Assignee: Sean Owen
Priority: Minor
Right now, several tests don't seem to pass when run with Java 8 (at least on
Java 8). The failures are benign, and just due to tests looking for
too-specific values or expecting things like a certain ordering of hashmaps.
The tests can easily be made to pass both Java 8 and Java 6/7 at the same time
by either relaxing the tests in a principled way, or accepting either output of
two equally valid ones as correct.
(There's also one curious compilation failure in Java 8, related to generics.
It is fixable by changing to a more explicit declaration that should be
equivalent. It should be entirely equivalent at compile time, and of course, at
run time. I am not sure it's not just a javac bug, but, might as well work
around when it's so easy.)
