JsonUtil.unbox with null values

[Nicolas Peltier]

Hey Karl,

have some weird NPE [0] in sling pipes' JsonUtil when "unboxing" null
values, but lambda make it hard to debug really :-/

i'm happy to fix it, but should i just create & fix a pipes bug in
that project, i saw several static unbox in sling project?

is there a plan to have one more central JsonUtil.unbox ?

Nicolas

    JsonArray array = (JsonArray)
JsonUtil.parse("[{\"foo\":\"foo\",\"bar\":null}]");
    Object binding = JsonUtil.unbox(array.get(0));
}
