RHEL找出java實際安裝路徑

顯示安裝的是jdk11

顯示的版本卻是jdk8
[root@localhost ]# java -version
openjdk version "1.8.0_282"
OpenJDK Runtime Environment (build 1.8.0_282-b07)
OpenJDK 64-Bit Server VM GraalVM CE 21.0.0.2 (build 25.282-b07-jvmci-21.0-b06, mixed mode)


後來才發現是graalvm底下的jdk
[root@localhost ]# readlink -f $(which java)
/graalvm/bin/java
