ArrayIndexOutOfBoundsException With PooledByteBufAllocator Recycler implementaion

See original GitHub issue

Issue Description

While trying to write an HttpMessage using HTTP1 with HttpClientCodec i.e HttpObjectEncoder, Netty is throwing an ArrayIndexOutOfBounds Exception while trying to allocate buffer for headers. Exception seems to be happening in the PooledByteBufAllocator Recycler Implementation.
