Bug ID: 57592
Summary: numberwriter example: Response status 500,
asyncOperation() not valid for request with state
DISPATCHED
Product: Tomcat 8
Version: 8.0.18
Hardware: PC
Status: NEW
Severity: normal
Priority: P5
Component: Connectors
Assignee: dev@tomcat.apache.org
Reporter: knst.koli...@gmail.com
First noted this when testing 8.0.20 release candidate, but this is also
reproducible with 8.0.18 and 8.0.17.
http://markmail.org/message/rkkdl6publsievvi
Steps to reproduce:
1) go to /examples/servlets/nonblocking/numberwriter with a web browser
2) look into access log
Expected: status 200
Actual: status 500 for APR, NIO, NIO2. (BIO is OK)
This issue depends on timing. E.g. it reproduces for me consistently with HTTP
connector, but not HTTPS connector. It does not reproduce in some other
configurations.
3) Add the following line to logging.properties to enable FINE logging for
Coyote:
org.apache.coyote.level=FINE
The following is observed in the log:
for Nio 2, Tomcat 8.0.20:
