Describe the bug
I communicate with downstream server , At beginning I send request with okhttp manutally and everything is ok , when i integrate spring gateway mvc，i got 500 error like form encode escape % etc. after i dive into deep code , i found an odd Request Filter RemoveContentLengthRequestHeadersFilter

why we need remove content-lengh ,i can't understand the meaning of the comment on top.

// jdk http clients seem to not like having this copied from the initial request. // urlconnection fails with form url encoded
