PPTX showing NPE
When Tika tried to read metadata from a PPTX that has a null creation date, an
NPE occurs in PackagePropertiesPart.getDateValue.
private String getDateValue(Nullable<Date> d) {
if (d == null) {
return "";
}
SimpleDateFormat df = new SimpleDateFormat(
"yyyy-MM-dd'T'HH:mm:ss'Z'");
return df.format(d.getValue());
}
Although the code checks whether d is null, it appears that d.getValue()
returns null, and an NPE is thrown in SimpleDateFormat.format:
Caused by: java.lang.NullPointerException
at java.util.Calendar.setTime(Calendar.java:1075)
at java.text.SimpleDateFormat.format(SimpleDateFormat.java:876)
