Scala Error starting REPL "class file violated"

Question

Every time after starting Scala 2.9.2 REPL (Java HotSpot (TM) 64-bit server VM, Java 1.8.0-ea), the first line of code execution causes an error:

scala> 1 + 2 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 1484) 

Later, during a further evaluation, there were no such errors in the current REPL instance.

Does anyone have any suggestions on how to handle this behavior?

Answer 1

Try choosing another alternative java provider:

 $ sudo update-alternatives --config java 

There are several alternative java options (providing / usr / bin / java).

Revision: Scala is now available for Java 8 :-)
