错误在我降级到Jersey 2.27之后不再出现。然而...
...在这个错误消失之后，我遇到了另一个错误：[java.lang.AbstractMethodError: javax.ws.rs.core.UriBuilder.uri(Ljava/lang/String;)Ljavax/ws/rs/core/UriBuilder;][1]。我已经检查了我的pom.xml依赖项，它们是正确的。问题是，我之前以非Maven方式设置了一个Eclipse项目，并且只是将`Jersey 1.x`库（最初使用的版本）放在了`/src/main/webapp/WEB-INF/lib`文件夹中，然后在将项目更改为Maven项目并升级`Jersey`到版本`2.32`后，我没有将它们删除（忘记了）。因此，较旧版本的jar文件被复制到了`../ECLIPSE-WORKSPACE/.../org.eclipse.wst.server.core/tmp1/wtpwebapps/MY-APP/WEB-INF/lib`目录中，与`Jersey 2.x`的jar文件一起。真是愚蠢。
记住这一点，并回忆起我之前注意到的：
> 我觉得奇怪的是IllegalArgumentException在这一行被抛出：
> Constants.checkAsmExperimental(this);
我认为最初的问题并不是我当时使用的Jersey版本（2.32），而是Jersey 1.x和Jersey 2.x的jar文件最终出现在了类路径中。目前，我已将Jersey版本升级到2.32，一切都正常工作。所以，可能Jersey 2.3根本没有bug。

The error did not appear anymore after I downgraded to Jersey 2.27. However...
... after this error disappeared, I got another one: [java.lang.AbstractMethodError: javax.ws.rs.core.UriBuilder.uri(Ljava/lang/String;)Ljavax/ws/rs/core/UriBuilder;][1]. I had checked my pom.xml dependencies and they were correct. The problem was that I had previously had setup an Eclipse project in non-Maven manner and had simply put `Jersey 1.x` libraries (which I was initially using) in `/src/main/webapp/WEB-INF/lib` folder and I did not remove them (forgot) after I changed the project to Maven one and upgraded `Jersey` to version `2.32`. Therefore older version jars were being copied to `../ECLIPSE-WORKSPACE/.../org.eclipse.wst.server.core/tmp1/wtpwebapps/MY-APP/WEB-INF/lib` directory with `Jersey 2.x` jars. Silly me.
Having that in mind and remembering that I noticed earlier
> I find it strange that IllegalArgumentException is thrown in line
> Constants.checkAsmExperimental(this);
I think the original issue was not with Jersey version I had used at the time (which was 2.32), but with Jersey 1.x and Jersey 2.x jar files ending up in the classpath. Currently, I have upgraded Jersey version to 2.32 and everything works. So, probably there is no bug in Jersey 2.3 at all.
