Hello,
I'm getting an IllegalArgumentException when calling
org.apache.poi.hmef.Attachment.getContents(). I'm using 1.14. My source
code and log output:
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-scratchpad</artifactId>
<version>3.14</version>
</dependency>
HMEFMessage hmefMessage = new HMEFMessage(is);
for (Attachment attachment : hmefMessage.getAttachments())
{
......
logger.warn("Datei " + attachment.getLongFilename() + "
wurde nicht verarbeitet, da kein PDF");
logger.info("Info using code from
https://poi.apache.org/hmef/ :");
for (TNEFAttribute attr : attachment.getAttributes())
{
logger.info("A.TNEF : " + attr);
}
for (MAPIAttribute attr : attachment.getMAPIAttributes())
{
logger.info("A.MAPI : " + attr);
}
if (logRejectedStream(attachment.getContents(),
attachment.getLongFilename()))
{
rejectedFiles.add(attachment.getLongFilename()); //
IllegalArgumentException :-(
}

The poi source code is:
https://svn.apache.org/viewvc/poi/trunk/src/scratchpad/src/org/apache/poi/hmef/Attachment.java?view=markup
138 /**
139 * Returns the contents of the attachment.
140 */
141 public byte[] getContents() {
142 TNEFAttribute contents =
getAttribute(TNEFProperty.ID_ATTACHDATA);
143 if(contents == null) {
144 throw new IllegalArgumentException("Attachment corrupt
- no Data section");
145 }
146 return contents.getData();
147 }
From my understanding, IllegalArgumentException is rather for
programming errors.
I've now changed my code to check
getAttribute(TNEFProperty.ID_ATTACHDATA) myself, but shouldn't
getContents() rather throw a checked exception? Or have a javadoc that
explains what to do first before calling the method?
Sorry I can't offer the Winmail.dat file, it has confidential data. So
maybe we'll never know for sure if the file was corrupt.
The "lost" attachments are not really important, they are company /
department logos. I was downloading them to decide whether they are
important or now, and then calculate an MD5 digest and then ignore them
in the future.
I also tried HMEFDumper... here's an output for a "corrupt" attachment:

Surprisingly "ID Attachment" is not empty. I tried saving the
attr.getData() contents but it isn't an image file. It is some non
compressed data and has "Picture (Device Independent Bitmap)" near the end.
