Issue/Introduction

I just noticed my OI connector started failing a few weeks ago - i tried restarting but same error

Seen in OIConnector.log

 

[ERROR] 2025-11-08 03:09:04.546 [pool-6-thread-47] RemoteDataConnectionImpl - Error issuing REST request ( https://oi-host.com:443/tas/graph/storeAsync ). Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

……….

After stopping and restarting the connector, we now see this message in wrapper-<DATE>.log:

 

The configured wrapper.java.command could not be found, attempting to launch anyway: /usr/lib/jvm/java-17-openjdk-17.0.15.0.6-2.el8.x86_64/bin/java

ADVICE | wrapper  | 2025/12/11 12:45:26 | Advice:

ADVICE | wrapper  | 2025/12/11 12:45:26 | Usually when the Wrapper fails to start the JVM process, it is because

ADVICE | wrapper  | 2025/12/11 12:45:26 | of a problem with the value of the configured Java command.  Currently:

ADVICE | wrapper  | 2025/12/11 12:45:26 | wrapper.java.command=/usr/lib/jvm/java-17-openjdk-17.0.15.0.6-2.el8.x86_64/bin/java

ADVICE | wrapper  | 2025/12/11 12:45:26 | Please make sure that the PATH or any other referenced environment

ADVICE | wrapper  | 2025/12/11 12:45:26 | variables are correctly defined for the current environment.
