Decode failures using ora:getAttachmentContent or ora:getAttachmentProperty functoins

Question

Hi,
I have a BPEL process that is started using the ums-email-adapter. The bpel process should abstract each attachment in the email and upload it to an ORacle BPM 12c ACM case.
In the basis I got this working, with pretty simple emails. But in other cases, where the email is more complex the abstraction of the attachment using the ora:getAttachmentContent or ora:getAttachmentProperty function fail with a error like:
<bpelFault><faultType>0</faultType><subLanguageExecutionFault xmlns="http://docs.oasis-open.org/wsbpel/2.0/process/executable"><part name="summary"><summary>An error occurs while processing the XPath expression; the expression is ora:getAttachmentProperty('Content-Type', 'ReceiveMessage_ReceiveNotification_InputVariable','body', '/ns2:message/ns2:attachment[$AttachmentId]').</summary></part><part name="detail"><detail>XPath expression failed to execute.
An error occurs while processing the XPath expression; the expression is ora:getAttachmentProperty('Content-Type', 'ReceiveMessage_ReceiveNotification_InputVariable','body', '/ns2:message/ns2:attachment[$AttachmentId]').
The XPath expression failed to execute; the reason was: java.lang.RuntimeException: Failed to decode properties string ,att.contentId=1,Content-Type=multipart/related;
    boundary "---- _Part_188_790028878.1418047669530",.
Check the detailed root cause described in the exception message text and verify that the XPath query is correct.
</detail></part><part name="code"><code>XPath expression failed to execute</code></part></subLanguageExecutionFault></bpelFault>
This exception is not even catched by the faultHandler, so I can't even simply ignore or handle it.
Has anyone an idea on what causes this and how to work around it? Or simply detect this case before calling the the ora:getAttachmentContent or ora:getAttachmentProperty functions?
Btw: I used the simple 'String' option in configuring the ums-email adapter. Tried with the Opaque option as well, but same issue there.
Thanks in advance.
Regards,
Martien

I found a workaround myself: Darwin-IT: ora:getAttachmentProperty: Failed to decode properties string.
