Hi, I'm using HttpComponents httpClient 4.5.2 and I'm really struggling
with understanding an exception that I recieve from Apache Tomcat. The
exception is:
org.apache.catalina.connector.ClientAbortException: java.io.IOException:
APR error: -104
After hours of debugging and thinking, I start to believe the problem is
coming from HttpComponents HttpClient. The reason is that I'm using an
ehcache to cache the Http responses, and in turn add the cache in a
custom CachingHttpClient. Then I'm writing this response to a
HttpServletResponse in my custom servlet, using the entity.writeTo method.
So when I receive a response from the cache, the response is gzipped,
and the writeTo method of the GzipCompressingEntity is (I think) is
creating the following issue:
Because of this issue:
https://issues.apache.org/jira/browse/HTTPCLIENT-1484 the outputStream
is being closed by the HttpClient. However, it is the only Entity that
does so, if I'm reading the source code correctly.
wrappedEntity.writeTo(gzip);
// Only close output stream if the wrapped entity has been
// successfully written out
gzip.close();
I beleive this APR ClientAbortException on Tomcat is caused by this
premature closing of the outputstream of the HttpservletResponse. It
might not be a bug, since it should not matter what Tomcat expects, but
I thought I should ask / report anyway. I hope my question / comments
make sense, because I'm still investigating the cause of this issue, and
I might be completely wrong.
