Summary: Uploaded file is corrupted when using HTTP 2 and JSSE
Product: Tomcat 10

Hardware: PC
Status: NEW
Severity: normal

Example application
Upload of a larger file via multipart HTML form can corrupt uploaded file in
case Tomcat is configured to use SSL connector with HTTP 2 and the native
library is disabled. This error depends on which web browser is used.
How to reproduce:
1) Configure Tomcat to used SSL
I used self signed certificate in a JKS file. In server.xml enable ssl
connector with HTTP 2 protocol.
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol"
maxThreads="150" SSLEnabled="true"
maxParameterCount="1000">
<UpgradeProtocol overheadDataThreshold="0"
className="org.apache.coyote.http2.Http2Protocol" />
<SSLHostConfig>
<Certificate certificateKeystoreFile="keystore.jks"
certificateKeystorePassword="changeit" type="RSA" />
</SSLHostConfig>
</Connector>
and remove line with "AprLifecycleListener" from it.
2) Use attached application on url https://localhost:8443/TestUpload
3) Upload larger file
The file will be stored in %CATALINA_HOME%\webapps\TestUpload
I used zip file with 6MB jar in it and the zip was damaged. But you can also
create larger text file and compare contents.
4) Use different browsers.
When I used Chrome and Edge the file was corrupted. Firefox froze. But when I
used Waterfox the problem newer happened.
The problem newer happens when Apache Tomcat Native library is enabled.
The problem newer happens when HTTP 2 is disabled.
