Class DuplicateFrameEliminator

java.lang.Object

org.objectweb.asm.MethodVisitor

org.jacoco.core.internal.instr.DuplicateFrameEliminator

class DuplicateFrameEliminator
extends org.objectweb.asm.MethodVisitor

Eliminates consecutive stackmap frame definitions which causes ASM to create invalid class files. This situation occurs when the original class files contains additional stackmap frames at unexpected offsets, which is case for some class files compiled with ECJ.
