[Bug 59054] New: CrawlerSessionManagerValve is not serializable, and
throws exception when passing itself as sessionAttribute
https://bz.apache.org/bugzilla/show_bug.cgi?id=59054
Bug ID: 59054
Summary: CrawlerSessionManagerValve is not serializable, and
throws exception when passing itself as
sessionAttribute
Product: Tomcat 7
Version: 7.0.64
Hardware: All
OS: All
Status: NEW
Severity: critical
Priority: P2
Component: Connectors
Assignee: dev@tomcat.apache.org
Reporter: kubas121@o2.pl
During first request to the application when user agent matches crawler pattern
the execution reaches the point where it tries to store itself in
sessionAttribute (s1.setAttribute(this.getClass().getName(), this)). Since
CrawlerSessionManagerValve does not implement Serializable it throws exception:
java.lang.IllegalArgumentException: setAttribute: Non-serializable attribute

I was able to fix this bug by modyfing source code to implement Serializable
interface.

Thanks for reply. Can you explain how distributed enviroment can influence
this behaviour.
The class is not serializable so any StandardSession.setAttribute() call with
it as a parameter will end up throwing exception, won't it? Apart from that I
am not using distributed enviroment.

You should only see this error in a distributed environment.
The CrawlerSessionManagementValve isn't intended to be distributed so I have
added to the list of attributes that are excluded from this process. This fix
has been applied to 9.0.x (for 9.0.0.M4 onwards), 8.0.x (for 8.0.33 onwards)
and 7.0.x for 7.0.69 onwards.

If you have further questions, please use the user list, bugzilla is not a
support forum. Thanks.
