Description

When unmounting a page, I get a NullPointerException from BookmarkableMapper.java:189.

Snippet of the StackTrace:

java.lang.NullPointerException
at org.apache.wicket.core.request.mapper.BookmarkableMapper.matches(BookmarkableMapper.java:189)
at org.apache.wicket.core.request.mapper.BookmarkableMapper.parseRequest(BookmarkableMapper.java:98)
at org.apache.wicket.core.request.mapper.AbstractBookmarkableMapper.mapRequest(AbstractBookmarkableMapper.java:288)
at org.apache.wicket.request.mapper.CompoundRequestMapper.unmount(CompoundRequestMapper.java:254)
at org.apache.wicket.protocol.http.WebApplication.unmount(WebApplication.java:391)
at ...

In CompoundRequestMapper.java:250 a Request is created, which returns null on getClientUrl() (see CompoundRequestMapper.java:291). This getClientUrl() is used as "baseUrl" at BookmarkableMapper.java:179 which leads to the NPE at BookmarkableMapper.java:189 "baseUrl.getSegments()".
