Luc Maisonobe resolved MATH-1224. --------------------------------- Resolution: Fixed Fix Version/s: 3.6 4.0 Fixed in git repository for the remaining part (ODE package). > NullPointerExceptions not documented in some classes > ---------------------------------------------------- > > Key: MATH-1224 > URL: https://issues.apache.org/jira/browse/MATH-1224 > Project: Commons Math > Issue Type: Bug > Affects Versions: 3.3, 3.5 > Environment: Mac OS X, Java 6-8 > Reporter: Cyrille Artho > Priority: Minor > Labels: documentation, easyfix, easytest, newbie > Fix For: 4.0, 3.6 > > Attachments: Report6.java, Report7.java > > Original Estimate: 40m > Remaining Estimate: 40m > > In general, the need to initialize newly constructed objects with more data > is now documented, but we have found two cases where a NullPointerException > is thrown because of missing data. > The documentation should be updated to reflect this. This is similar to > issues report in MATH-1116 but concerns classes that are not going to be > deprecated (as far as we can tell). > I have previously posted this as a new comment on issue 1116, but that > comment has not elicited any response. As the original issue is one year old, > I post this bug as a new issue. > Below is the code that produces the two cases: > org.apache.commons.math3.ode.nonstiff.HighamHall54Integrator var1 = new > org.apache.commons.math3.ode.nonstiff.HighamHall54Integrator(0.0d, 0.0d, > 0.0d, 0.0d); > double[] var2 = new double[] { 0.0d }; > var1.computeDerivatives(0.0d, var2, var2); // NPE > new > org.apache.commons.math3.stat.correlation.SpearmansCorrelation().getCorrelationMatrix(); > // NPE -- This message was sent by Atlassian JIRA (v6.3.4#6332)
