RE: CloudStack Compile Error
Posted by Donal Lafferty <do...@citrix.com>.
FYI, this happens when you accidentally install different versions of Java for compile and runtime.
E.g.
Compile with javac...
root@mgmtserver:~/github/cshv3/tools/apidoc# which javac
/usr/bin/javac
root@mgmtserver:~/github/cshv3/tools/apidoc# ls -al /usr/bin/javac
lrwxrwxrwx 1 root root 23 Jul 16 19:58 /usr/bin/javac -> /etc/alternatives/javac
root@mgmtserver:~/github/cshv3/tools/apidoc# ls -al /etc/alternatives/javac
lrwxrwxrwx 1 root root 43 Jul 16 19:58 /etc/alternatives/javac -> /usr/lib/jvm/java-7-openjdk-amd64/bin/javac
Run with java...
root@mgmtserver:~/github/cshv3/tools/apidoc# which java
/usr/bin/java
root@mgmtserver:~/github/cshv3/tools/apidoc# ls -al /usr/bin/java
lrwxrwxrwx 1 root root 22 Jul 16 17:15 /usr/bin/java -> /etc/alternatives/java
root@mgmtserver:~/github/cshv3/tools/apidoc# ls -al /etc/alternatives/java
lrwxrwxrwx 1 root root 46 Jul 16 17:15 /etc/alternatives/java -> /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java
Fix?
In my case, I wanted to try out the version 7 JRE.
sudo apt-get install openjdk-7-jre
This wasn't enough. I also had to purge the version 6 JRE
apt-get purge openjdk-6-*
