macOSのJavaインストール場所

• コンパネのJavaでアップデートされてるjavaはどこにあるんじゃい？という話

java_home -V で見てもなし。

• Javaコンパネとバージョン違います。

sh-3.2$ /usr/libexec/java_home -V
Matching Java Virtual Machines (1):
    1.8.0_131, x86_64:	"Java SE 8"	/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home

/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home
sh-3.2$

Javaコンパネで指定されてるのはここです。

• /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/

sh-3.2$ /Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java -version
java version "1.8.0_171"

Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)
sh-3.2$

ふつうに使うと...

sh-3.2$ java -version
java version "1.8.0_131"
