Hi,
Since a few weeks, I have lots of tests failures due to matrix formats.
I'm not sure exactly when this started, but I think this may be related
to MATH-831 and the fix introduced as of r1364775 in late July. This
changed the behaviour of toString in AbstractRealMatrix. The difference
is that despite the default number of digits is set to one, matrix
entries that happen to be integer are displayed as "1" or "0" and not as
"1.0" or "0.0" as expected by the Junit tests.
The tests that fail for me are:
MultivariateSummaryStatisticsTest: testToString,
SparseRealMatrixTest: testToString
SynchronizedMultivariateSummaryStatisticsTest: testToString
Array2DRowRealMatrixTest: testToString
BlockRealMatrixTest: testToString
They fail both when I use eclipse and when I use maven from the command
line. Eclipse is configured to use Sun Java 1.5.0_22 JVM. Maven is
configured with OpenJDK 1.6.0_24. I use a Linux computer running Debian,
configured with the French locale (but the tests do reset the locale
themselves).
Here is the output from Maven:
