Bug ID: 62258
Summary: getOutputStream() has already been called for this
response with caught IOException and jsp error page
Product: Tomcat 9
Version: 9.0.6
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: clem...@guillaume.bzh
Target Milestone: -----
Created attachment 35839
--> https://bz.apache.org/bugzilla/attachment.cgi?id=35839&action=edit
log of the Exception
When an IOException that occurred while writing the response doesn't bubble up
the through the Servlet.service and a jsp error page is specified, the
following Exception will happen when tomcat tries to render the jsp:
2018-04-04 18:33:04 SEVERE org.apache.catalina.core.ApplicationDispatcher
invoke Servlet.service() for servlet [jsp] threw exception
java.lang.IllegalStateException: getOutputStream() has already been called for
this response
[...]
2018-04-04 18:33:04 SEVERE org.apache.catalina.core.StandardHostValve custom
Exception Processing ErrorPage[errorCode=0, location=/error.jsp]
org.apache.jasper.JasperException: java.lang.IllegalStateException:
getOutputStream() has already been called for this response
It's reproductible with a ClientAbortException: call a page that take long time
to write the response and interrupt that call (ctr+c on curl). See this project
for example: https://github.com/guillaumecle/tomcat-error-page
This doesn't happen in 9.0.5, only 9.0.6. I beleive it's related to bug 41007
