This is an example piece of code from openflowplugin tests.

ActionSetNwSrcReactorTest.java:45

new Ipv6Builder().setIpv6Address(new Ipv6Prefix("1234:5678:9abc:def1:2345:6789:abcd:ef12")).build(),

This passes a prefix without a /X to the Ipv6Prefix constructor.

This should not work. But it does - test passes in stock openflowplugin from helium.
