Using xstream to generate objects from table definitions.

[Graham Berks]

Hi, do you have an example to follow ?

Going from RC13 to RC16 has broken our tests with the current xstream
conversions we are doing.

Thanks

Specifically the @XStreamAlias we use to convert names fails.

Has something been removed to introduce these types to xstream ?

Not sure what you mean.

Did you try RC14 and RC15? Might be easier to spot where the
regression was introduced.

Also - need some code to reproduce the regression. Can you file a
ticket please? Or better - a pull request with a failing feature, for
example in the java-calculator examples module.

RC15 gave

java.lang.NullPointerException
at cucumber.runtime.Utils.isInstantiable(Utils.java:
18)
at
cucumber.runtime.java.ClasspathMethodScanner.scan(ClasspathMethodScanner.java:
27)
at
cucumber.runtime.java.JavaBackend.loadGlue(JavaBackend.java:58)
at cucumber.runtime.Runtime.<init>(Runtime.java:67)
at cucumber.runtime.Runtime.<init>(Runtime.java:54)
at cucumber.runtime.Runtime.<init>(Runtime.java:50)
at cucumber.junit.Cucumber.<init>(Cucumber.java:56)

but that went away in RC16.

The specific error was came in RC16 ( could of been hidden by the
above issue ), will knock up an example and raise an issue.

Thanks

Must be some weird transitive dependency in our build that kicked in
during a change in RC versions.

So far can't repo in a fork with java-calc with code at RC21-Snapshot.

Odd, it's not obvious in our build.

The issue is with the embedding of xstream within cuke.

If I use the annotation @XStreamAlias via com.thoughtworks.xstream.annotations import it fails.

Using the embedded cucumber.runtime.xstream.annotations.XStreamAlias it's fine.

Thanks

Yep. There is a note about this in History.md
