[Bug 69016] New: HttpURLConnection getOutputStream createCapacityException
https://bz.apache.org/bugzilla/show_bug.cgi?id=69016
Bug ID: 69016
Summary: HttpURLConnection getOutputStream
createCapacityException
Product: Tomcat 9
Version: 9.0.89
Hardware: All
OS: All
Status: NEW
Severity: blocker
Priority: P2
Component: Util
Assignee: dev@tomcat.apache.org
Reporter: raffaele.tripodo@3ware.it
Target Milestone: -----
Hello,
a simple code to download pdf file (generated by a servlet) is working fine in
Apache Tomcat 9.0.87, but the same exact code throws an excpetion in Apache
Tomcat 9.0.89.
This is the code
URL url = URI.create(address).toURL();
HttpURLConnection conn = (HttpURLConnection)
url.openConnection();
if (!params.isEmpty())
{
byte[] postData = String.join("&",
params).getBytes(Charset.forName("UTF-8"));
int postDataLength = postData.length;
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setRequestMethod("POST");
conn.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
conn.setRequestProperty("Content-Length",
Integer.toString(postDataLength));
conn.setRequestProperty("Charset", "utf-8");
conn.setConnectTimeout(1000 * 15);
conn.setReadTimeout(1000 * 30);
// here is the error!
try (DataOutputStream dos = new
DataOutputStream(conn.getOutputStream()))
{
dos.write(postData);
dos.flush();
dos.close();
}
}
try (InputStream in = conn.getInputStream())
{
if (tempFile)
{
file =
File.createTempFile("getUrlFile", ".tmp");
try (FileOutputStream out = new
FileOutputStream(file))
{
copyBinaryStream(in, out);
}
}
content = getTextStream(in);
}
The same code works fine in previous version.

DataOutputStream out = new DataOutputStream(conn.getOutputStream())

--- Comment #7 from Remy Maucherat <re...@apache.org> ---
The cause of the "bug" is that marTrailerSize is configured to -1. This used to
be allowed and used to set a "no limit" as documented, so the trailers would
really be unlimited in size. This is usually not a very good idea BTW.
However, following the last major refactoring to improve functionality (
https://github.com/apache/tomcat/commit/cbed8e1836962d43120b81ae99d8d1b349265749
), -1 is no longer an allowed value. The documentation was not fixed probably
as a result of not realizing the commit introduced that change. I'll have to
fix the documentation since there's no way to restore the previous capability.

We probably need an "InvalidArgumentException" with a nice error message as
well as a documentation-fix.
That error message is not readable by "normal people" :)

Also, an example of the full HTTP request including headers and body would be
very helpful, here.

And the sample code used to generate the response that triggers this behaviour?
Looks like the Servlet isn't writing a response body so we need to see that
code.

Dropping priority to normal. It really was a blocker, I'd expect a faster
response to our questions.
I'll note at this point that without the requested information, this issue will
eventually get resolved as WORKSFORME given that the issue appears to be that
the Servlet isn't writing a response body.

I've been busy and away from office in these weeks. When I posted this issue, I
just wanted to submit the problem to the community.
Anyway I confirm the presence of this problem in the releases after 9.0.87
(last one working). I experiend the same problem with 9.0.89 and 9.0.90.
Beacuse you have closed this request as resolved, I guess you have found the
problem too. I hope you'll address the situation and release the fix in the
next releases.
Thanks for your support
