Description

I tried to add metadata as shown in AddMetadataFromDocInfo.java. There's also the line

basicSchema.setModifyDate( info.getModificationDate() );

but I get a NullPointerException at this line:

java.lang.NullPointerException
at org.apache.jempbox.impl.DateConverter.toISO8601(DateConverter.java:221)
at org.apache.jempbox.xmp.XMPSchema.setDateProperty(XMPSchema.java:249)
at org.apache.jempbox.xmp.XMPSchemaBasic.setModifyDate(XMPSchemaBasic.java:266)

because the info.getModificationDate() returns null. It would be better to catch null parameters in the metadata set methods.

Workaround:

if (pddi.getModificationDate() != null)

{ basicSchema.setModifyDate(pddi.getModificationDate()); }

//else: avoid NPE
