        + *
      • The first four bytes must contain the right magic number (0xCAFEBABE). + *
      • All recognized attributes must be of the proper length. + *
      • The class file must not be truncated or have extra bytes at the end. + *
      • The constant pool must not contain any superficially unrecognizable information. + *
      + * A more in-depth documentation of what pass one should do was written by + * Philip W. L. Fong: + *
        + *
      • the file should not be truncated. + *
      • the file should not have extra bytes at the end. + *
      • all variable-length structures should be well-formatted: + *
          + *
        • there should only be constant_pool_count-1 many entries in the constant pool. + *
        • all constant pool entries should have size the same as indicated by their type tag. + *
        • there are exactly interfaces_count many entries in the interfaces array of the class file. + *
        • there are exactly fields_count many entries in the fields array of the class file. + *
        • there are exactly methods_count many entries in the methods array of the class file. + *
        • there are exactly attributes_count many entries in the attributes array of the class file, + * fields, methods, and code attribute. + *
        • there should be exactly attribute_length many bytes in each attribute. + * Inconsistency between attribute_length and the actually size of the attribute content should be uncovered. + * For example, in an Exceptions attribute, the actual number of exceptions as required by the number_of_exceptions field + * might yeild an attribute size that doesn't match the attribute_length. Such an anomaly should be detected. + *
        • all attributes should have proper length. In particular, under certain context (e.g. while parsing method_info), + * recognizable attributes (e.g. "Code" attribute) should have correct format (e.g. attribute_length is 2). + *
        + *
      • Also, certain constant values are checked for validity: + *
          + *
        • The magic number should be 0xCAFEBABE. + *
        • The major and minor version numbers are valid. + *
        • All the constant pool type tags are recognizable. + *
        • All undocumented access flags are masked off before use. Strictly speaking, this is not really a check. + *
        • The field this_class should point to a string that represents a legal non-array class name, + * and this name should be the same as the class file being loaded. + *
        • the field super_class should point to a string that represents a legal non-array class name. + *
        • Because some of the above checks require cross referencing the constant pool entries, + * guards are set up to make sure that the referenced entries are of the right type and the indices + * are within the legal range (0 < index < constant_pool_count). + *
        + *
      • Extra checks done in pass 1: + *
          + *
        • the constant values of static fields should have the same type as the fields. + *
        • the number of words in a parameter list does not exceed 255 and locals_max. + *
        • the name and signature of fields and methods are verified to be of legal format. + *
        + *
      + * (From the Paper + * The Mysterious Pass One, first draft, September 2, 1997.) + * + *

      However, most of this is done by parsing a class file or generating a class file into BCEL's internal data structure. + * Therefore, all that is really done here is look up the class file from BCEL's repository. + * This is also motivated by the fact that some omitted things + * (like the check for extra bytes at the end of the class file) are handy when actually using BCEL to repair a class file + * (otherwise you would not be able to load it into BCEL).

Monitor-specific behaviour is not simulated.

      + * + * Conventions: + * + *

      Type.VOID will never be pushed onto the stack. Type.DOUBLE and Type.LONG + * that would normally take up two stack slots (like Double_HIGH and + * Double_LOW) are represented by a simple single Type.DOUBLE or Type.LONG + * object on the stack here.
