Could not load classfile

I am getting the below runtime exception when I try to run a Java program

Exception in thread "main" java.lang.RuntimeException: Could not load    classfile: java.util.concurrent.ConcurrentMap

The command used is

java -cp soot-csi.jar:../lib/soot-2.5.0.jar blah.soot.SomeClass

Since ConcurrentMap is one of the basic JRE classes, I was thinking that it is being caused by the rt.jar file not being able to be found/present in the jdk. So I checked my $JAVA_HOME variable and it does point to a JDK where the rt.jar resides inside the lib folder. So the structure is like this.

/usr/lib/jvm/java-1.7.0-openjdk.x86_64/lib/rt.jar
where $JAVA_HOME = /usr/lib/jvm/java-1.7.0-openjdk.x86_64

Anyone know how to solve this issue?

Solution

Try to use absolute path to java executable like

$ /usr/lib/jvm/java-1.7.0-openjdk.x86_64/bin/java -cp ...

Probably a soley java executes an older version that do not include ConcurrentMap.
