I hope someone could give some tips to fix this potential SSL issue.

I am using Oracle JMC5.5.2 bundled with Oracle JDK8u231 and getting this exception when:

  • going to Help > Check for updates or
  • Help > Install New Software ...

enter image description here

As a result, this client based on Eclipse is unable to contact the server.

Is there any way to troubleshoot this issue? it seems the certificate sent by the server is expired.

Available Software Sites has no reference to https:

Also, I tried the same with Oracle JMC8, which has a completely different graphic interface, but that issue isn't replicated.

Now based on Enable Java to permit expired certificate if the expired cert is added to the trusted key store file, that validation will pass. The thing is JMC is based on Eclipse, and the configuration files are under <JAVA_HOME>\lib\missioncontrol\configuration folder. If the javax.net.debug=ssl option is added to the config.ini file, where can I get the corresponding output?

Is there any way to tell this JMC(based on Eclipse) to write the stdout to a log file, thus I could know what cert is received and which cacerts is used?

Thank you very much!!

UPDATE:

I am not going to insist on the old JMC5.5.2 anymore, and just moved to JMC8 (where that issue isn't seen). I've spent last week studying the new interface, and it's awesome. The line of development of JMC6 is completely different. It was redone from the scratch, not only affecting its core, but the UI as well. It’s a completely brand new concept. It introduced a sophisticated automated analysis report, a different layout, lots of filters, and the performance was improved dramatically.

  • Output could be on `/.metadata/.log` – LMC Jun 24 '21 at 22:12
  • Just installed JMC and notably, the update site is `http` protocol, not `https`. http://download.oracle.com/technology/products/missioncontrol/updatesites/base/6.0.0/eclipse/. Try removing the `s` in the `Available software site` entry. You will need to add the certificate to your jvm cacert database otherwise. – LMC Jun 24 '21 at 22:49
  • There is no such workspace folder for JMC5.5.2 packed with Oracle JDK1.8u231. Note that if I don't know where the log is (if any), it won't be possible to know what certs are required, and which trusted keystore file is used. Did you download the same version or the latest Oracle JMC8 where this issue doesn't occur? – Mario.Cadiz Jun 26 '21 at 18:35
  • I just went to Eclipse Marketplace and installed the latest JMC. – LMC Jun 26 '21 at 20:49

I switched to JMC8. It has the same and much more.
