Cannot apply multiple (implicit) conversions in assignment

[Richard Kolb]

Hi Volker,

Thanks. I was hoping for more of an informal community talk before I go
there.To be honest I need to know I am not asking a uninformed question.

I've been looking at the javap bytecode I don't see what this is not
possible in createObjectLongAutoBoxing.

Long.valueOf() supports both a int and a long.
Perhaps the problem is more complex than that.

regards,
Richard
