Jasmin HelloWorld示例失败

Question

I'm having a problem executing a newly compiled HelloWorld.j from the jasmin-2.4 distribution.

I downloaded jasmin-2.4. I can compile ok using:

java -jar jasmin.jar examples\\HelloWorld.j

the output is:

Generated: NoJad\\j.class

When I execute the newly compiled program:

java NoJad.j

an exception is thrown:

Exception in thread "main" java.lang.VerifyError: (class: NoJad/j, method: main signature: ([Ljava/lang/String;)V) Expecting to find object/array on stack Could not find the main class: NoJad.j. Program will exit.

I'm inclined to believe that this is a bug in the HelloWorld.j example. Perhaps a new verifier has caught a bug???

Note 1: the pre-compiled HelloWorld.class in the distribution works as expected.

Note 2: I'm using this version of java java version "1.6.0_24" Java(TM) SE Runtime Environment (build 1.6.0_24-b07) Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02, mixed mode)

Here's the HelloWorld.j file from the distribution:

   return

Answer 1

The problem is the HelloWorld.j file is bogus. See this thread: http://sourceforge.net/projects/jasmin/forums/forum/349052/topic/3330588
