After upgrading to Java8, javac still shows 1.7

Question

I'm having issues upgrading from JDK 1.7 -> 1.8 on OSX. The upgrade has completed, but javac still returns 1.7 as the version. I've downloaded JDK 8_u5 from Oracle's homepage, and run the installer. I've also taken the following steps, post-install: ``` > export JAVA_HOME=`/usr/libexec/java_home -v 1.8` (Executed in my .bashrc file) > echo $JAVA_HOME /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/Home > javac -version javac 1.7.0_21 > $JAVA_HOME/bin/javac -version javac 1.7.0_21 > $JAVA_HOME/bin/java -version java version "1.8.0_05" Java(TM) SE Runtime Environment (build 1.8.0_05-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode) ``` I've gone through and removed Java 1.7 (and all other JDK versions), and then re-run the installer: ``` > ls /Library/Java/JavaVirtualMachines jdk1.8.0_05.jdk ``` Still no use, javac reports the version as 1.7.0_21 ``` > which javac /usr/bin/javac > ls -ltra /usr/bin/javac [snipped] /usr/bin/javac -> /System/Library/Frameworks…

Accepted Answer

If `/usr/libexec/java_home -v 1.8.0_05 --exec javac -version` returns the correct version, then your problem is with:

```
/System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK
```

With a privileged user execute:

```
cd /System/Library/Frameworks/JavaVM.framework/Versions/
rm CurrentJDK
ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_05.jdk/Contents/ CurrentJDK
```

Also check this answer on Super User for dynamically switching JDK versions.

Update: I guess I've found the culprit!

Try this:

```
rm -rf ~/Library/Java/Extensions
sudo rm -rf /Library/Java/Extensions
```
