> Back in 2013, the api (now core) went through a major refactoring to remove direct dependency to javax.mail: https://github.com/apache/cxf/commit/6ae8f4afe219581938c0020612212faa3e770064 Custom code for attachment deserialization was added, but unfortunately that seems to be writing a lot of char[] to the memory, because of a lot of String instances being created for parsing the attachment inputstream into the headers TreeMap. The process could be optimized to avoid useless string / char[] copies. It also seems that the special handling of lines starting with spaces there is over complicated and covering a condition that can never be true.
