Lack JUC

[zhangtianxiao]

I build miniJvm based Windows & java8 & mingw64, then I run a java demo

[INFO]jvm inited
class not found:java.util.concurrent.ConcurrentMap.class
class not found:java.util.concurrent.ConcurrentHashMap.class
class not found:java.util.concurrent.TimeUnit.class

How to add JUC to minijdk? Thanks!

[zhangtianxiao]

I found some class under juc in minijdk, but no ConcurrentHashMap and others. Ha

yes, these classes are not full jdk8 api spec.
