Apache SkyWalking Component

OAP server (apache/skywalking)

What happened

our app java version is jdk-25 jdk-21 jdk-8
I use java agent apache/skywalking-java-agent:9.6.0-java8 apache/skywalking-java-agent:9.6.0-java17 apache/skywalking-java-agent:9.6.0-java21
every version has the same problems:

not only MinimalHttpClient the plugin, also this
rm -f /agent/agent/plugins/apm-httpClient-4.x-plugin-.jar
rm -f /agent/agent/plugins/apm-httpclient-commons-.jar
rm -f /agent/agent/plugins/apm-httpasyncclient-4.x-plugin-.jar
rm -f /agent/agent/plugins/apm-kafka-plugin-.jar
rm -f /agent/agent/plugins/apm-kafka-commons-.jar
rm -f /agent/agent/activations/apm-toolkit-logback-1.x-activation-.jar

when i use the apache/skywalking-java-agent:8.16.0-java17 ,there is no issues.

so I think the bytebudy frame has some bugs
