Error cli.System.MissingMethodException: Method not found: '?'. when running exe converted from jar.

I have a simple runnable jar which uses bsh-2.1.1 to do some dynamic script evaluation.

After conversion using ikvmc (using the latest 8.10.2 release), when I try to run the resulting executable I get the following call stack,

    at java.lang.reflect.Method.invoke(Method.java:486)
    at bsh.Reflect.invokeMethod(Reflect.java:157)
    at bsh.Reflect.invokeObjectMethod(Reflect.java:93)
    at bsh.Name.invokeMethod(Name.java:854)
    at bsh.BSHMethodInvocation.eval(BSHMethodInvocation.java:67)
    at bsh.BSHPrimaryExpression.eval(BSHPrimaryExpression.java:94)
    at bsh.BSHPrimaryExpression.eval(BSHPrimaryExpression.java:39)
    at bsh.Interpreter.eval(Interpreter.java:681)
    at bsh.Interpreter.eval(Interpreter.java:764)
    at bsh.Interpreter.eval(Interpreter.java:753)
    at com.alphinat.test.Main.main(Main.java:11)

BTW the script passed to the eval method is 'value.equals("true")' so nothing complex in terms of code, it's a simple "equals" between two strings (value is assigned a string with the interpreter object used).

Any help appreciated. Thanks.

Just adding a little bit more details. I managed to debug in VS, and reached the following line, in Method.java, where the exception is thrown,

return ma.invoke(obj, args, ikvm.internal.CallerID.getCallerID());

At that point, obj is the string "false", args has one entry with the string "true". And obj is,

____java_lang_String__equals

That is the name reported for the object.

What is ma?

[apn-hroussel]

My bad, ma, the MethodAccessor, is actually

__FastMethodAccessor__java_lang_String__equals

whereas obj is the string "false".

There are angle brackets around FastMethodAccessor that were removed by the editor in my previous post.

Any suggestion on how to debug this?
