[CLJ-1399] missing field munging when recreating deftypes serialized in to byte code Created: 02/Apr/14 Updated: 02/Apr/14
to embed deftypes in the bytecode the compiler emits the value of each field, then emits a call to the deftypes underlying class's constructor.
to get a list of fields the compiler calls .getBasis.
the getBasis fields are the "clojure" level field names of the deftype, which the actual "jvm" level field names have been munged (replacing - with _, etc), so the compiler tries to generate code to set values on non-existent fields
you can work around this by using field names that don't require munging. a solution might be just calling munge in the emission of field sets of ITypes

this patch fixes the issue on the latest master for me

FWIW, this was precipitated by real experience (I think I created the refheap paste). The workaround is easy (don't use dashes in field names of deftypes you want to return from data reader functions), but I wouldn't expect anyone to guess that that wasn't already oversensitized to munging edge cases.
