IT28951: ISOLATE THE CLASSLOADING OF EMAIL NODES

APAR status

• Closed as program error.

Error description

• The classloader which is used to load the Java mail API is not
  isolated, this means that if there are customer deployed flows
  which themselves use the Java Mail API then this can clash with
  the versions of the classes loaded by the EmailInput and
  EmailOutput nodes.
  
  This could lead to unexpected behaviour including errors such as
  the following:
  
  BIP4973E: EmailInput node 'nodeName' in message flow 'FlowName'
  has received an email with content type 'multipart/mixed;
  boundary="boundaryId"' and internal type
  'javax.mail.internet.MimeMultipart', which the EmailInput node
  is not able to process.

Problem conclusion

• The Email Input and Email Output Nodes now use an isolated class
  loader preventing this error from occurring.
