Summary: NullPointerException in Http11OutputBuffer
Product: Tomcat 8
Version: 8.5.20
Hardware: PC
OS: Linux
Status: NEW
Severity: major
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org

Target Milestone: ----
Hello, this has been happening on ALL 8.5.* versions (I've been upgrading to
the newest version for a while now) and possible for a long time before that.
Jersey's version is 2.25.1, Tomcat is 8.5.20. This is the stacktrace:
java.lang.NullPointerException: null

...
What we're doing in "Contents.java:146" is something like:
EntityTag entityTag = getEntityTag(content);
ResponseBuilder responseBuilder =
request.evaluatePreconditions(entityTag);
if (responseBuilder == null) {
// cached resource did change -> serve updated content
responseBuilder = createResponseBuilder(range,
content).tag(entityTag);
}
asyncResponse.resume(responseBuilder.build());
This "content" thing is practically an InputStream - i.e. with this request a
blob is returned. The funny thing is that this happens ALWAYS when returning
"tiff" images. Not sure if this matters of course or if the problem isn't
actually in something from our side. But anyways, this should not blow up with
a NPE. :)
Please tell me if you need any more information.
