Annotation Type IgnoreNonStaticTraceComponent

@Target(FIELD)
@Retention(RUNTIME)
public @interface IgnoreNonStaticTraceComponent

Indicates that a non-static TraceComponent field should be ignored by the Liberty bytecode instrumentation tool. This annotation is used in cases where a TraceComponent must be instance-specific (non-static) for legitimate reasons, such as when different instances need different trace channels or configurations.

Without this annotation, the instrumentation tool will issue a warning and fail instrumentation when it encounters a non-static TraceComponent field, as the standard pattern requires TraceComponent fields to be declared as private static final.

Example usage:

 public class MyClass {
     // Dummy static TraceComponent to satisfy instrumentation
     private static final TraceComponent tc = Tr.register(MyClass.class);
     
     // Instance-specific TraceComponent that won't trigger instrumentation errors
     @IgnoreNonStaticTraceComponent
     private final TraceComponent instanceTc;
     
     public MyClass(String channelName) {
         this.instanceTc = Tr.register(channelName, MyClass.class, TRACE_GROUP);
     }
 }
