java.util.concurrent in JDK 1.4

[dema rogatkin]

I remember that Sun provided collection classes for JDK 1.1 users as a separate package. Is there something similar for classes from java.util.concurrent to be used under JDK 1.4? Generally I'm interested in ThreadPoolExecutor with ConcurrentLinkedQueue.

Download the jar file from this page:

Thanks. But I have no clue how to make it working under 1.4

C:\Project Files\arbat\src\java\1.4\poa\org\arbat\eventchannel\EventChannelImpl.java:12: cannot acces
s java.util.concurrent.LinkedBlockingQueue
bad class file: C:\Project Files\arbat\jsr166\lib\jsr166.jar(java/util/concurrent/LinkedBlockingQueue
.class)
class file has wrong version 50.0, should be 49.0
Please remove or make sure it appears in the correct subdirectory of the classpath.
import java.util.concurrent.LinkedBlockingQueue;
