Actors don't work with Java 1.5

There are two distributions, 1.5 and 1.6. Are you sure you got the 1.5 distribution?

hi,

using a recent nightly from scala, my previously working code breaks with

java.lang.NoSuchMethodError: java.util.concurrent.locks.LockSupport.park(Ljava/lang/Object;)V
  and
java.lang.NoClassDefFoundError: java/util/concurrent/RunnableFuture

when calling the actor method... seems some java 1.6 stuff sneaked in here?

ciao, -sciss-

Veni, vidi, veterni.

i have always been using http://www.scala-lang.org/scala-eclipse-
plugin-nightly ... is there a separate eclipse plug-in site for java
1.5?

thanks, -sciss-

At the moment, no ... there probably should be.

What JDK are you using to build your application? Even if the IDE code
was built with 1.6 you should be able to select 1.5 for building your
own projects.

The question is the Scala distribution being used. A 1.6 Scala distribution won't work with Java 1.5, particularly concerning Actors.
