특정 표준 log4j2 플러그인을 비활성화하는 방법

Question

Android에서 Log4j2를 사용하려고하는데 다음 스택 추적으로 실패합니다. Android에는 javax.naming 지원이 없으며 log4j2에이 플러그인이 필요하지 않습니다. Log4j2 JNDI 플러그인을 어떻게 비활성화 할 수 있습니까? (또는 다른 표준 플러그인)

Answer 1

RC-2를 사용하고 있습니까? log4j2 Jira 이슈 추적기에서이 문제를 제기하여 곧 출시 될 2.0 버전에서 수정 될 것입니다.

Answer 2

동일한 문제가 발생하여 JNDI와 비슷한 문제가 발생했습니다. JIRA https://issues.apache.org/jira/browse/LOG4J2-703을 코드 및 스택 트레이스와 함께 생성했습니다.
