Spring WebClient is not using Proxy for the latest version of spring-security-oauth2-client-5.3.4.RELEASE

[kmariappan2016]

I could not able to connect to OAuth2 Resource behind proxy if I use the latest spring-security-oauth2-client-5.3.4.RELEASE.

I am using the reactor netty httpclient to set the proxy as follows.
HttpClient httpClient = HttpClient.create().tcpConfiguration(tcpClient -> tcpClient.proxy(
proxy -> proxy.type(ProxyProvider.Proxy.HTTP).host(proxyHost).port(Integer.valueOf(port)).build()));
ClientHttpConnector connector = new ReactorClientHttpConnector(httpClient);
return WebClient.builder().clientConnector(connector).filter(oauth2FilterFunction).build();

But if I use spring-security-oauth2-client-5.3.0.RELEASE, I can able to connect via Proxy but the token is not associated with each request.

Advice me if I am doing anything wrong.

@kmariappan2016 Based on my understanding, you are not able to call a protected resource using spring-security-oauth2-client 5.3.4 (with proxy configuration). Correct? However, it works in 5.3.0?

If this is the case, what is the difference in your configuration between 5.3.0 and 5.3.4?

[kmariappan2016]

There is no change in configuration(proxy) between 5.3.0 and 5.3.4. I am keeping the same config.
Its not using the proxy config if I migrate to 5.3.4.

Let me know if any further details required.

Thanks,

@kmariappan2016 Can you please provide a minimal reproducible sample via a GitHub repo and then I can help troubleshoot.

[kmariappan2016]

Unfortunately I can not provide the code via GitHub as my organization policy blocks it.

I am connecting a resource behind corporate proxy and I have the proxy config as follows using Reactor HTTP Netty.
HttpClient httpClient = HttpClient.create().tcpConfiguration(tcpClient -> tcpClient.proxy(
proxy -> proxy.type(ProxyProvider.Proxy.HTTP).host(proxyHost).port(Integer.valueOf(port)).build()));

	ClientHttpConnector connector = new ReactorClientHttpConnector(httpClient);
	
	return WebClient.builder().clientConnector(connector).filter(oauth2FilterFunction).build();

I thought its netty reactor issue, but if I switch to 5.3.0 of spring webclient it started working.
