Issue/Introduction

ACC starts but UI does not come up.

Seeing many jetty errors .

Environment

Release : 10.7.0

Component : APM Agents

Resolution

1) Downgrade Java. Determining Using Agent works but not acceptable

 2)  workaround to disable "RSASSA-PSS":

Open ${JAVA_HOME}/jre/lib/security/java.security and find jdk.certpath.disabledAlgorithms add RSASSA-PSS to the end of the list:

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, \EC keySize < 224, 3DES_EDE_CBC, anon, NULL, RSASSA-PSS

Additional Information

There are no JVM settings to change this. Issue appears to be local to customer environment since not seen before.
