Scala repl throws error

When I type scala on the terminal to start the repl, it throws this error

scala> [init] error: error while loading AnnotatedElement, 
class file '/usr/lib/jvm/java-8-oracle/jre/lib/rt.jar
(java/lang/reflect/AnnotatedElement.class)' 
is broken (bad constant pool tag 15 at byte 2713)

When I hit enter and type println("hello, world"), it again throws this

error: error while loading CharSequence, 
class file '/usr/lib/jvm/java-8-oracle/jre/lib/rt.jar
(java/lang/CharSequence.class)' is broken
(bad constant pool tag 15 at byte 1501)

I am using Ubuntu 14.04 and java -version gives

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)

Downgrading JDK version to 7 solved this issue for me. Here is the solution: https://askubuntu.com/questions/761127/how-do-i-install-openjdk-7-on-ubuntu-16-04-or-higher

Either update to a newer scala version (2.10.3+) or downgrade java to java 6/7. As you have seen in the output, 2.9.2 was here long before java 8 was introduced (Copyright 2002-2011, LAMP/EPFL), so they don't work well together.

This duplicate question contains exact instructions on ubuntu's java downgrade.

You might have to run it with JDK 7 or 6
