[Tomcat] Unrecognized VM option 'PrintGCDateStamps'

# 오류

톰캣 실행경로(/bin)에 setenv.sh 를 생성하고 JVM 옵션을 추가로 부여했다. (아래 CATALINA_OPTS)

톰캣을 실행하니 Unrecognized VM option 'PrintGCDateStamps' 가 발생한다.

# 원인

Tomcat 실행하면서 JVM 실행옵션 중 'PrintGCDateStamps' 라는 옵션때문에 에러가 났다.

뭐하는 옵션인지는 사실 잘 모르겠으나, 이를 무시한다는 옵션을 추가해줌으로써 해결했다.

 

# 해결

Either add the following JVM option to the setenv.sh or setenv.bat file, or convert the GC options to the new Xlog format.

-XX:+IgnoreUnrecognizedVMOptions
