LocalVariableSorter

Hi,

I'm currently facing an issue with the LocalVariableSorter. The
following exception is raised:

java.lang.IllegalStateException: ClassReader.accept() should be called
with EXPAND_FRAMES flag
   at org.objectweb.asm.commons.LocalVariablesSorter.visitFrame(Unknown
Source)
   at org.objectweb.asm.tree.FrameNode.accept(Unknown Source)
   at org.objectweb.asm.tree.InsnList.accept(Unknown Source)
   at org.objectweb.asm.tree.MethodNode.accept(Unknown Source)
   at
de.kl.uni.cs.nehmer.setup.bci.FullLogBCIMethodAdapter.visitEnd(FullLogBCIMethodAdapter.java:73)
   at org.objectweb.asm.ClassReader.accept(Unknown Source)
   at org.objectweb.asm.ClassReader.accept(Unknown Source)

   at java.lang.ClassLoader.loadClass(Unknown Source)
   at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
   at java.lang.ClassLoader.loadClass(Unknown Source)

although the expand frames flag is set:

ClassReader classReader = new ClassReader(bytes);
ClassWriter classWriter = new ClassWriter(classReader,
ClassWriter.COMPUTE_FRAMES);
PrintWriter printWriter = new PrintWriter(new
FileOutputStream("classOutput.txt", true));
TraceClassVisitor traceClassVisitor = new TraceClassVisitor(classWriter,
printWriter);
BCIClassAdapter classAdapter = new BCIClassAdapter(traceClassVisitor);
classReader.accept(classAdapter, ClassReader.EXPAND_FRAMES);

Within the BCIClassAdapter a MethodAdapter is instantiated and visits
each method doing some transformations. In the visitEndMethod of the
MethodAdapter I call the accept(localVariableSorter) to chain the
visitor call just after my transformations are done. Any ideas or
suggestions?

Best regards
Nikolas
