That usually mean very beginning of the method.
Most of the transformations we are doing insert code at the beginning
method before line number label marker.
Basically any transformation that emits new code at
MethodVisitor+.visitCode() will cause this.
To work around we need to change those transformations to do something
like this:
void visit*Insn(..) { // all other visit methods for bytecode
instructions only
if(!started) { // to handle case when there is no debug info
emitCodeAtMethodStart();
}
super.visit*Insn(..);
}
void visitLineNumber(...) {
if(!started) {
emitCodeAtMethodStart();
}
super.visitLineNumber(...);
}
visit emitCodeAtMethodStart() {
started = true;
... emit code here
}
The AdviceAdapter may seem look similar, but it mainly meant for
emitting code at the beginning of constructors. I still need to check if
it handle line numbers for methods.
