The specific failures are:

Error:  Failures: 
Error:    HDF5SaverTest.testPartitionedWriting:73
Error:    HDF5SaverTest.testPartitionedWriting2:86
Error:    HDF5SaverTest.testSave2d:62
Error:    HDF5SaverTest.testSave4d:53

They can be reproduced by the following steps:

1. Clone labkit-ui
2. Check out tag labkit-ui-0.4.0
3. Edit the pom.xml, changing the parent pom-scijava version to 40.0.0, and removing all the overridden version property values from the <properties> section.
4. Run the build using mvn -Dbigdataviewer-core.version=10.6.3 clean test.

Whereas step 4 without the new bigdataviewer-core version (mvn clean test) does not exhibit these four test failures.

I tested also the current master branch (juglab/labkit-ui@01a5c80) with the same POM edits as above, and mvn -Dbigdataviewer-core.version=10.6.3 clean test has the same test failures there, whereas mvn clean test succeeds on my system.
