PM19507: IF THE CLEAR METHOD IS NOT CALLED ON A BNFHEADER OBJECT THAN AN UNEXPECTED ERROR AND/OR FFDC CAN BE SEEN ON THE HTTP CHANNEL

Fixes are available

APAR status

Closed as program error.

Error description

During the destroy of a BNFHeaders object the clear method may
not be called. This results in the object not being properly
reset. Since this object is pooled for reuse, the next request
which uses this object may get processed incorrectly. This could
 result in an unexpected exception and/or FFDC generated from
the HTTP Channel
