Composite metatdata with JS client not working properly

[nofelkad]

I am using Spring Boot: 2.2.3.RELEASE

Rsocket springboot server throws an exception for routing metadata which is part of composite metadata

java.lang.IndexOutOfBoundsException: readerIndex(1) + length(105) exceeds writerIndex(23): UnpooledSlicedByteBuf(ridx: 1, widx: 23, cap: 23/23, unwrapped: PooledUnsafeDirectByteBuf(ridx: 0, widx: 231, cap: 231))

with js client with composite metadata

     this.socket
         .requestResponse({
           data:  Buffer.from(JSON.stringify(scannerReq)),
           metadata: encodeAndAddWellKnownMetadata(
                           encodeAndAddCustomMetadata(
                             Buffer.alloc(0),
                             TEXT_PLAIN.string,
                             Buffer.from('Hello World')
                          ),

                           MESSAGE_RSOCKET_ROUTING,
                          Buffer.from('irl.user.location.user1')
                     )
         })

i have incorporated this changes as well.

Thanks.
