ClassFormatError in Twitter4J

Question

I have a program that updates a twitter account when somebody is connecting to the server. From wednesday till this morning the program worked fine. Now I'm getting this exception:

Exception in thread "main" java.lang.ClassFormatError: Unknown constant tag 133 in class file java/util/Arrays$ArrayList
    at java.util.Arrays.asList(Arrays.java:3355)
    at twitter4j.auth.OAuthAuthorization.toParamList(OAuthAuthorization.java:371)

    at twitter4j.TwitterImpl.post(TwitterImpl.java:1764)
    at twitter4j.TwitterImpl.updateStatus(TwitterImpl.java:447)

The program uses twitter4j for posting on twitter. I got the newest jar for twitter4j, released today and I have updated to the latest jvm, but I'm still having this problem.

Does anybody know what's wrong?

Thx

您应该使用最新的twitter api jar重新编译代码，很可能他们已经更改了其api的界面，并且您的代码需要更新。
