Problem building in Centos 6

[mircea-vutcovici]

When running make I receive the following error:

src/java/AttachOnce.java:25: cannot access com.sun.tools.attach.VirtualMachine
bad class file: com/sun/tools/attach/VirtualMachine.class(com/sun/tools/attach:VirtualMachine.class)
class file has wrong version 52.0, should be 50.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
import com.sun.tools.attach.VirtualMachine;
                           ^

Full output:

I run a strace -fe file make and it is finding tools.jar file:

[pid  2128] open("/usr/java/jdk1.8/include/../lib/tools.jar", O_RDONLY) = 5

Adding $JAVA_HOME/bin in the path fixed the issue.

PATH=/usr/java/jdk1.8.0_60/bin:$PATH JAVA_HOME=/usr/java/jdk1.8.0_60/ cmake .
make
