JavaMail: File extension omitted by invoking part.getFileName

[Ulrich Heeger]

Hi everyone
I have a question: When I invoke the getFileName()-method on a part and the fileName contains ISO 8859-1 character set, then it might be that the file extension is omitted, when the fileName contains whitespaces.
Example:
Filename: Comments f�r test.doc
Result of part.getFileName():

 =?iso-8859-1?Q?Comments=5Ff=FCr=5Ftest?=   

Filename: Commentsf�rtest.doc
Result of part.getFileName():

 =?iso-8859-1?Q?Commentsf=FCrtest.doc?=   

Is this a bug? Do you know a workaround to get the filename with the file extension?

Thanks a lot in advance
Greetings
Ulrich
