我只想使用 Oracle 的 Java 7 JVM 来确保 Eclipse 尽可能快地运行。这是怎么回事?我应该选择哪一个?
$ sudo update-alternatives --config java
There are 4 choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-7-oracle/jre/bin/java 1055 auto mode
