----------------------------------
Summary: Checking on null values in HTTP Header for protected JWS
header
Key: CXF-8035
URL: https://issues.apache.org/jira/browse/CXF-8035
Project: CXF
Issue Type: Bug
Components: JAX-RS Security
Affects Versions: 3.3.1
Reporter: Jan Bernhardt
Assignee: Colm O hEigeartaigh
If a HTTP header is set but without a value, the current implementation causes
a Nullpointer exception.
[https://github.com/apache/cxf/blob/master/rt/rs/security/jose-parent/jose-jaxrs/src/main/java/org/apache/cxf/rs/security/jose/jaxrs/JoseJaxrsUtils.java]
Line 79 needs to be changed from
{code:java}
if (headerValues != null) {{code}
to:
{code:java}
if (headerValues != null || headerValues.isEmpty() || headerValues.get(0) !=
null) {{code}
In my case the header was set but without any values causing
{{headerValues.get(0)}} to return {{null}}. The following code invokes
{{.toString()}} on this null value causing the Nullpoiniter.
