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)
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 (

This duplicate question contains exact instructions on ubuntu’s java downgrade.
remove the scala 2.9.2 using terminal
sudo apt-get remove scala
download the latest scala from scala website
Installation instruction are giving on this link
You might have to run it with JDK 7 or 6
Downgrading JDK version to 7 solved this issue for me.
Here is the solution:
