//@olsen: fix for bug 4467428:
// Debugging under jdk 1.3.1 shows the problem that any breakpoints
// in PC classes are ignored if the added jdo methods do NOT have a
// non-empty line number table attribute, no matter whether the
// 'Synthetic' attribute is given or not. However, this doesn't
// seem to comply with the JVM Spec (2nd edition), which states
// that the synthetic attribute _must_ be specified if no source
// code information is available for the member:
//
// 4.7.6 The Synthetic Attribute
// ... A class member that does not appear in the source code must
// be marked using a Synthetic attribute. ...
//
// 4.7.8 The LineNumberTable Attribute
// The LineNumberTable attribute is an optional variable-length
// attribute in the attributes table of a Code (see 4.7.3)
// attribute. It may be used by debuggers to determine which
// part of the Java virtual machine code array corresponds to a
// given line number in the original source file. ... Furthermore,
// multiple LineNumberTable attributes may together represent a
// given line of a source file; that is, LineNumberTable attributes
// need not be one-to-one with source lines.
//
// Unfortunately, if we do both, adding the synthetic attribute and
// a (dummy) line number table on generated methods, jdk's 1.3.1 javap
// fails to disassemble the classfile with an exception:
//
// sun.tools.java.CompilerError: checkOverride() synthetic
//
// So, to workaround these problems and to allow for both, debugging
// and disassembling with the jdk (1.3.1) tools, we pretend that the
// generated jdo methods have source code equivalents by
// - not adding the synthetic code attribute
// - providing a dummy line number table code attribute
