-------------------------------------

             Summary: Can't use custom FTPParser on OSGI
                 Key: CAMEL-9094
                 URL: https://issues.apache.org/jira/browse/CAMEL-9094
             Project: Camel
          Issue Type: Bug
          Components: camel-ftp
    Affects Versions: 2.15.2
            Reporter: Tom Cunningham


Using a custom ftp entry parser on OSGI results in an exception because of the use of Class.forName in commons-net DefaultFTPFileEntryParserFactory :

Camel can work around this by creating a ParserFactory that is used if Camel is being used in an OSGI environment that simply extends the DefaultFTPFileEntryParserFactory and uses the Camel class resolver rather than Class.forName.
