[GitHub] [skywalking] markusleevip opened a new issue #6674: Ignoring url using the trace-ignore-plugin plug-in throw a java.lang.NullPointerException
markusleevip opened a new issue #6674:
URL: https://github.com/apache/skywalking/issues/6674
### Bug
- Which version of SkyWalking, OS, and JRE?
OS:CentOS Linux release 8.2.2004
JAR :openjdk version "1.8.0_252"
- What happened?
Ignoring url using the trace-ignore-plugin plug-in throw a java.lang.NullPointerException
/apm-sniffer/apm-agent-core/src/main/java/org/apache/skywalking/apm/agent/core/context/ContextManager.java
```
/**
* Recommend use ContextManager::stopSpan(AbstractSpan span), because in that way, the TracingContext core could
* verify this span is the active one, in order to avoid stop unexpected span. If the current span is hard to get or
* only could get by low-performance way, this stop way is still acceptable.
*/
public static void stopSpan() {
final AbstractTracerContext context = get();
// Throw NullPointerException
stopSpan(context.activeSpan(), context);
}
```

Fixing belongs to the whole community, including yourself.
Taking action rather than a hope. Hope means no one is doing this now.
