Yes, that would have saved others some effort. >> >> Both of these could happen with any Java version. >> >>> Or is this a hint for making Java 8 the minimum supported >>> version for the next release? >> >> >> That is not a valid conclusion from the evidence. > > > How do you draw that conclusion? Because there is no proof that the failure is caused by using Java 7 rather than because the test uses a specific version of the Java 7 JVM. JVM crashes tend to be specific to particular implementations. It any case, a test that fails with a JVM crash is not a failure of the code being tested but of the JVM itself. > More to the point, my request is: What to do to fix the negative > advertisement for the project which this Travis issue propagates > (see badge): > https://github.com/apache/commons-math No idea. Ask a Travis guru. The negative publicity belongs to the specific Java 7 JVM which is crashing. Commons Math should really be praised for exposing the bug. I think this just shows that automated checks are only useful if it is clearly understood how the checkers measure success/failure. > > > Regards, > Gilles > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org > For additional commands, e-mail: dev-h...@commons.apache.org > --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
