Hi,

      We are using tomcat-8.5.34. One of our client code is sending a POST 
request with HTTP header parameter "Host", as an empty string. And 8.5.34 
version of tomcat is rejecting the connection with a 400 Error. After 
debugging, we found that the parseHost API in 
org.apache.coyote.AbstractProcessor is throwing an InvalidArgumentException 
(Seems to be introduced in 8.5.31). Then we checked out the latest tomcat code 
from SVN and found that the issue has been already addressed ( 
https://bz.apache.org/bugzilla/show_bug.cgi?id=62739 ) . So, we hope, the fix 
would be available in 8.5.35.

May I know, when is the next official tomcat release planned? So that we can 
decide on how to handle this issue in our product.

Thanks,

Mani
