-------------------------------------
Summary: Header::getField with class cast can fail with NPE
Key: MIME4J-307
URL: https://issues.apache.org/jira/browse/MIME4J-307
Project: James Mime4j
Issue Type: Task
Components: dom
Reporter: Benoit Tellier
Fix For: 0.8.7
{code:java}
original.getHeader().getField("Sender", MailboxField.class)
{code}
On an email without a sender will yield:
{code:java}
java.lang.NullPointerException
at
org.apache.james.mime4j.message.AbstractHeader.getField(AbstractHeader.java:128)
at org.apache.james.mime4j.dom.MessageTest.test(MessageTest.java:446)
at
java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
{code}
That's a shame, the method is convenient.
To fix this, add a null check.
