worker contains unsupported properties
Product: Tomcat Connectors

Patch terminates native/common/jk_util.c:supported_properties array with NULL
The 1.2.26 was re-compiled with VS2008. The workers file contained accidentally
a worker property introduced by 1.2.27. The IIS connector crashes during
initialization with memory access error.
The problem is, that native/common/jk_util.c:supported_properties array does
not end with NULL. In case of wrong property, the pointer will go out of bounds
in
native/common/jk_util.c:jk_is_valid_property function.
The officail binary release DLL of 1.2.26 from Apache will print:
[error] jk_map.c (403): The attribute 'worker.gw1.ping_mode' is not supported -
please check the documentation for the supported attributes.
and does not cause crash. This could be because VC++ 6.0 (which is used for
official binary builds as I understand) uses different memory alignment/layout
or something else. Anyway, I think it is safer not to permit run pointer out of
array and explicitly mark the end of list with NULL.
Proposed fix is attached as patch.
