I noticed a couple of instabilities (in jdk13 and higher) in the test security/infra/java/security/cert/CertPathValidator/certification/LuxTrustCA.java .

The test sometimes fails when validating the “validity interval” of OCSP responses :
Example output is like :

certpath: OCSP response validity interval is from Wed Dec 04 01:05:27 CET 2019
certpath: Checking validity of OCSP response on: Wed Dec 04 01:39:15 CET 2019 <--------- default interval is system time “on” machine +/- 15 minutes , this is seen as valid by OpenJDK
  …
java.lang.RuntimeException: TEST FAILED: couldn't determine EE certificate status
                at ValidatePathWithParams.validate(ValidatePathWithParams.java:177)
                at LuxTrustCA.main(LuxTrustCA.java:186)

                at java.base/java.lang.Thread.run(Thread.java:832)


stdout contains :
Received exception: java.security.cert.CertPathValidatorException: Response is unreliable: its validity interval is out-of-date


Looks like there might be an issue on LuxTrust side, this should be checked (the problem is seen on various different test machines).
