Inconsistent build failure.

[sujithvm]

The project build fails inconsistently on Travis and Appveyor.
Tests fail inconsistently due to the following Runtime error.

HDF5-DIAG: Error detected in HDF5 (1.8.11) thread 140198367926016:
  #000: ../../../src/H5L.c line 813 in H5Lexists(): not a location
    major: Invalid arguments to routine
    minor: Inappropriate type
  #001: ../../../src/H5Gloc.c line 195 in H5G_loc(): invalid group ID
    major: Invalid arguments to routine
    minor: Bad value

Currently, Maven Surefire plugin is configured to ignore Test errors.
Investigate root cause of the issue.
