javax.net.ssl.SSLProtocolException: The certificate chain length (11) exceeds the maximum allowed length (10)

问题

I'm struggling since my java MVC web application started throwing an exception when trying to create a WebService that has an specific https address (https://barramento.caixa.gov.br/sibar/ManutencaoCobrancaBancaria/Boleto/Externo?xsd=xsd0).

After enabling the javax.net.debug I figured out that the root cause of the problem seems to be the length of the certificate chain of the server application where I'm trying to connect to.

In a first moment, I suspected from the TLS version, but using nmap I was able to find the version of TLS the server is using as well as the ciphers, and they are not the problem. The server suports TLS1.1. I've already configured my server to work with this version, but it did not help at all.

I've searched all over the web for some information that could help but I was not able to find anything at Google pointing to nothing even close to "javax.net.ssl.SSLProtocolException: The certificate chain length".

Her is the stacktrace:

This post clarified a lot and gave me some guidance to understand the problem. But was not enought.

Note: the stranger thing is that this problem happens when running my application from an ubuntu instance using Java 1.8.0_272. When run my application from a Windows machine (also using Java 1.8.0_272) it doesn't happen.

Is there any JVM argument or any other way of set the lengh of the allowed certificate chain?

Has anyone already faced something like that?

回答1:

As pointed by @dave_thompson_085, the actual chain is only 4. The problem was the many certificates sent by the server (also pointed by @dave_thompson_085).

Adding the "-Djdk.tls.maxCertificateChainLength=15" JVM argument solved the issue.

Thanks a lot @dave_thompson_085.
