Description
Invocation of dispose() method form another thread may cause crash in jpeg library
if reading is in progress. Same for jpeg writer: if writing operation is in progress,
then attempt to dispose writer instance form another thread may cause crash in jpeg
library.
Comments
EVALUATION Public method dispose() of jpeg image reader and jpeg image writer should be protected by thread locks to prevent concurrent change of reader/writer state.
