Redhat openjdk breaks tls in bamboo 7.1

We've been using bamboo with tls on port 8443 for years.  Redhat released openjdk and when we upgraded our bamboo server to it, none of the agents or browsers could communicate to 8443.  We are seeing a "err_ssl_protocol_error" message in chrome and the agents report " unsupported or unrecognized ssl message" in their logs.  We do have a proxy in front on port 443 that proxies to 8443 and that still works fine.

I've tried modifying file settings but nothing seems to be making a difference.  My concern is that I'm going to see the same issue with our other Atlassian servers.

Also, I upgraded to bamboo 7.1.4 but forgot to specify the bamboo.home directory in atlassian-bamboo/WEB-INF/classes/  When I went to the bamboo server on port 8443, it displayed the web page showing me the diagnostic page that shows the java version check and the bamboo.home setting and how to fix it so the tls issue happens after I specified the bamboo.home directory.

Had anyone else seen issues with upgrading to that version of openjdk on RHEL7?

Hi @doug_curtis,

It looks like you have stumbled onto this bug.

Glad to see that you managed to fix it by downgrading Java. If this was not an option, I was going to suggest the workaround proposed by my colleague in the bug report above.

Good news is that this has been fixed in Bamboo 7.2.0 already (that is yet to be released as of today).


Thanks for this.  This seems exactly like what I'm running into.  I'll play around with options specified in the bug report to verify.

Thanks again!

That's definitely what it was.  Disabling the RSASSA-PSS signature algorithm fixed the issue.  At least now if I HAVE to upgrade to u272, I have a solution for it.

Thanks for the quick response.

G'day Doug,

We're fairly confident you won't run into this with any other Atlassian products as it relates to a certain Bamboo dependency and how it's loading crypto providers. 



That's good news.  I was going to add RSASSA-PSS on my other Atlassian servers as a precautionary measure but I'm glad that it's probably not necessary.

Hi @doug_curtis ,

Please confirm and test the following.

  1. Custom configurations were migrated from the previous installation.
  2. Port 8443 is enabled in the server.xml .... Bamboo listens on 8085 by default.
  3. Unrecognized SSL message, plaintext connection? 

1.  Yes they were.  I only upgraded from 7.1.1 to 7.1.4 to see if it fixed the issue.  The only upgrade that broke bamboo was the openjdk upgrade.

2.  Yes.  We have a connector specified in the server.xml for port 8443 that references a keystore with the password.  This worked fine before the openjdk upgrade.

3.  I saw this in my searches and tried it but it didn't fix the issue.


I should also note that downgrading openjdk fixes the issue.  We don't run any custom jdk settings.  I've only started trying different jdk settings to see if it affects it.  It seems like either a TLS protocol or cipher issue.
