ClassNotFoundException when parsing .msg

GroupDocs.Parser Product Family

Hi all

When parsing a specific .msg file, we get the following exception:

java.lang.NoClassDefFoundError: com/groupdocs/parser/internal/o/b/cms/RecipientId

	at com.groupdocs.parser.internal.c.a.e.MailMessage.removeSignature(Unknown Source)

This is using groupdocs-parser 26.4 (java). I confirm that the class
com.groupdocs.parser.internal.o.b.cms.RecipientId
is NOT in the groupdocs-parser jar. There is however:
com.groupdocs.parser.internal.c.a.i.internal.bouncycastle.cms.RecipientId
and
com.groupdocs.parser.internal.c.a.ms.core.bc.cms.RecipientID

Is this a bug?

(Unfortunately I cannot provide the .msg file in question as it contains sensitive information)
