[Archive-access-discuss] java.lang.NullPointerException

[<Dom...@sw...>]

I get this java.lang.NullPointerException error message when I try to open
an archived url. However this error does not appear all the time. It seems
only urls that are redirected (Got an HTTP 302 response at crawl time) are
affected.

Does annyone has a clue and can give me a hint?


I have Wayback 1.6.0 installed on apache-tomcat-6.0.35, java version (JRE)
1.6.0 and use a cdx index

Thank you and best regards

Dominik
