can it handle abstract classes? i was trying to convert one. the .c is empty when I look at it.

Exception in thread "main" java.lang.NullPointerException: Cannot invoke "com.ebsee.classparser.ClassFile.getMethods()" because "cf" is null
at com.ebsee.j2c.ClassManger.findMethod(ClassManger.java:299)

我想基于该项目二次开发，但是由于您的项目未提供开源许可，担心著作权侵权。
请问，您是否有打算以什么样的形式对该项目进行开源授权呢？

Thank you for your previous reply in /mini_jvm
I have some problems when compile minijvm_rt.jar to C code

• I use intelliJ Idea to compile class2c.jar and run it to make /out/c .c file, it's ok
  but file generated "metadata.h" have struct struct java_lang_Class {InstProp prop; VMTable* vm_table; struct java_lang_ClassLoader* classLoader_3; struct java_lang_String* name_4; JArray * enumConstants_5; struct java_util_Map* enumConstantDirectory_6; s64 classHandle_7; struct org_mini_reflect_ReflectClass* refClass_8;};
  it's not compatible with default jvc.c, native_std.c : JObject *ins_of_Class_create_get(JThreadRuntime *runtime, JClass *clazz) { JClass *java_lang_class = g_procache.java_lang_class_raw->clazz; if (java_lang_class) { if (clazz->ins_of_Class) { return clazz->ins_of_Class; } else { struct java_lang_Class *ins = (struct java_lang_Class *) new_instance_with_class(runtime, java_lang_class); gc_refer_hold(ins); Java_java_lang_Class__init____V(runtime, ins); clazz->ins_of_Class = (__refer) ins; ins->classHandle_6 = (s64) (intptr_t) clazz;//todo , find it use field refer return (JObject *) ins; } } return NULL; }
  So I changed classHandle_6 to classHandle_7, before that vm/.c file could be compiled to .obj file

2. after that I use CMake to genarate Makefile, but it stuck when compile jvm.c file
   so I remove {GUI_FILES} in CMake, it ran OK, compiled all /out/c/*c file to obj
   But there are errors at last combination:

   Could you help me handle there problems. Thank you!
