IKVM编译的DLL中的IllegalArgumentException

Question

快速总结：

我的IKVM编译的JAR-to-DLL库与.NET项目中的一些方法和类一起工作，但一个特定的库抛出了一个异常，似乎表明我的IKVM.Runtime.jni试图将一个64位地址存储到一个32位变量中，而我希望整个系统是32位的。这会引发IllegalArgumentException。

首先,我编译log4j JAR：

~>ikvmc -target:library log4j-1.2.14.jar

IKVM.NET Compiler version 7.3.4830.0

note IKVMC0002: Output file is "log4j-1.2.14.dll"
warning IKVMC0100: Class "javax.jms.MessageListener" not found
...

大约有20个左右的警告处理javax.jms.*和javax.mail.*，但它似乎可以很好地编译。

我的项目有一个app.config，其中设置了ikvm：java.library.path和ikvm：java.class.path：

<appSettings>
    <add key="ikvm:java.library.path" value="C:\path\to\DLLs\for\JNI;" />
    <add key="ikvm:java.class.path" value="C:\path\to\config;C:\path\to\license;" />
</appSettings>

app.config还具有所有IKVM库的程序集绑定。

<罢工> 看起来Agnitio库将某个对象的地址存储在一个32位变量中，但IKVM库方法将其转换为一个64位地址，因此出现了IllegalArgumentException。网上的很多文档都说ikvm-native-*.dll决定JNI调用是以32位还是64位的方式进行，但我的jvm.dll或ikvm-native-win32-x86.dll似乎根本没有参与这个过程。对于如何解决这个问题（或者集成这个JAVA库的更好方法）有什么想法吗？

编辑：我最初的印象是不正确的。Ikvm-native-win32-x86.dll和jvm.dll在其32位版本中成功地包含在项目中。我现在有点不知道错误信息是什么了。

这很可能是本机代码中的bug。看起来它试图设置字段NativeMemoryJNI.ptrAddress，但它传递的是一个ArrayForNativeCode类型的对象，而不是NativeMemoryJNI（或子类）。
