In some scenarios, TIBCO ActiveMatrix BusinessWorks™ applications may encounter the error java.lang.NoClassDefFoundError: io/opentelemetry/context/ImplicitContextKeyed and fail to start after installing 5.15.1 HF02. This article explains how to fix the issue.

The error is caused by not having the library files required for OpenTelemetry support in the classpath. A defect has been logged for this - BW-19862. To resolve the issue, apply one of the workarounds given below.

1. Add %BW_HOME%/lib/palettes/otel to tibco.env.STD_EXT_CP in deployed application .tra file and restart the application

OR

2. Redeploy the application. BW_HOME/bin/bwenigne.tra has the entry %BW_HOME%/lib/palettes/otel in tibco.env.STD_EXT_CP so any new deployments will add it to the application .tra file.
