Replacement

Shows the difference in example code before and after the bug pattern is applied.

 import com.newrelic.api.agent.Trace;
 import org.springframework.scheduling.annotation.Scheduled;
 
 class A {
+  @Trace(dispatcher = true)
   @Scheduled(fixedDelay = 1)
   void scheduledButNotTraced() {}
 
   @Scheduled(fixedDelay = 1)
-  @Trace
+  @Trace(dispatcher = true)
   void scheduledButImproperlyTraced1() {}
 
   @Scheduled(fixedDelay = 1)
-  @Trace(dispatcher = false)
+  @Trace(dispatcher = true)
   void scheduledButImproperlyTraced2() {}
 
   @Scheduled(fixedDelay = 1)
-  @Trace(leaf = true)
+  @Trace(dispatcher = true, leaf = true)
   void scheduledButImproperlyTraced3() {}
 }

Identification

Shows code lines which will (not) be flagged by this bug pattern.
A //BUG: Diagnostic contains: comment is placed above any violating line.

import com.newrelic.api.agent.Trace;
import org.springframework.scheduling.annotation.Scheduled;

class A {
  void notScheduled() {}

  @Scheduled(fixedDelay = 1)
  // BUG: Diagnostic contains:
  void scheduledButNotTraced() {}

  @Scheduled(fixedDelay = 1)
  // BUG: Diagnostic contains:
  @Trace
  void scheduledButImproperlyTraced1() {}

  @Scheduled(fixedDelay = 1)
  // BUG: Diagnostic contains:
  @Trace(dispatcher = false)
  void scheduledButImproperlyTraced2() {}

  @Scheduled(fixedDelay = 1)
  @Trace(dispatcher = true)
  void scheduledAndProperlyTraced() {}
}

import org.springframework.scheduling.annotation.Scheduled;

class A {
  @Scheduled(fixedDelay = 1)
  void scheduledButNotTraced() {}
