java - Scala repl throws error -

-

when type scala on terminal start repl, throws 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)'  broken (bad constant pool tag 15 @ byte 2713)

when hit enter , type println("hello, world"), again throws this

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

i using ubuntu 14.04 , 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 newer scala version (2.10.3+) or downgrade java java 6/7. have seen in output, 2.9.2 here long before java 8 introduced (copyright 2002-2011, lamp/epfl), don't work together.

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

in program creating in python/pygame, screen.blit not working. in other programs have made, screen.blit works. error: traceback (most recent call last): file "c:...\main.py", line 46, in <module> screen.blit(sight.image, sight.rect) attributeerror: 'int' object has no attribute 'blit' the error in question caused screen variable being allocated integer instead of pygame.surface() object.perhaps accidentally rewrote variable somewhere? from can make of doing, seems stating position of blit full rect instead of coordinate. when do: screen.blit(sight.image,sight.rect) what program seeing is: screen.blit(sight.image,(sight.rect.x,sight.rect.y,sight.rect.width,sight.rect.height)) i assuming don't intend this. remember rect object consists of position, width , height. to correct code, put (sight.rect.x,sight.rect.y) location goes instead this: screen.blit(sight.image,(sight.rect.x,sight.rect.y)) the .x , .y corres
