Scala REPL startup error "class file is broken"
提问by Yehor Nemov
Every time after starting Scala 2.9.2 REPL (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0-ea) first line of code executing bring me an error:
每次启动 Scala 2.9.2 REPL (Java HotSpot(TM) 64-Bit Server VM, Java 1.8.0-ea) 后第一行代码执行都会给我一个错误：
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 further evaluation in current REPL instance no similar errors are occured.
稍后在当前 REPL 实例的进一步评估期间没有发生类似的错误。
Has anyone any suggestion how to handle this behaviour?
有没有人有任何建议如何处理这种行为？
