问题
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:
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.
Has anyone any suggestion how to handle this behaviour?
回答1:
Try to select other alternative provider java:
$ sudo update-alternatives --config java
There are some choices for the alternative java (providing /usr/bin/java).
Selection Path Priority Status
------------------------------------------------------------
0 /usr/lib/jvm/java-8-oracle/jre/bin/java 1071 auto mode
1 /usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java 1061 manual mode
2 /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1051 manual mode
* 3 /usr/lib/jvm/java-8-oracle/jre/bin/java 1065 manual mode
Press enter to keep the current choice[*], or type selection number:
EDITED: Scala is now abailable for Java 8 :-)
