Я обнаружил следующую проблему, когда запустил свой профилировщик 

BLOCKED CPU usage on sample: 62ms
org.apache.logging.log4j.core.layout.TextEncoderHelper.copyDataToDestination(ByteBuffer, ByteBufferDestination) TextEncoderHelper.java:61
org.apache.logging.log4j.core.layout.TextEncoderHelper.encodeTextWithCopy(CharsetEncoder, CharBuffer, ByteBuffer, StringBuilder, ByteBufferDestination) TextEncoderHelper.java:57

(или)

Большинство моих заблокированных потоков указывают на это. Кто-нибудь может мне помочь в этом? Я запускаю приложение mule, и когда я попытался откопать задержку в обработке mule, я обнаружил, что оно попало в блоки из-за log4j

Что я могу попытаться решить эту проблему?

Без дополнительной информации я бы сказал, что приложение ведет журнал регистрации или использует шаблон, требующий большой обработки, или их комбинацию.
