exception from asm.commons.LocalVariablesSorterremap

hi,

got a strange exception from mentioned class.. i'm actually using jarjar which
in turn is using asm-commons, but i'm 90% sure the exception is yours.. namely,
when i write:

    public void someMethod() {
        String line;
        // and use it later..


i get:

java.lang.IllegalStateException: Unknown local variable 1
	at com.tonicsystems.jarjar.asm.commons.LocalVariablesSorter.remap(Unknown Source)
	at com.tonicsystems.jarjar.asm.commons.LocalVariablesSorter.visitFrame(Unknown

	at
com.tonicsystems.jarjar.ext_util.JarProcessorChain.process(JarProcessorChain.java:31)
....

(never mind about the package names being renamed.. that's what jarjar is about)

Why i'm sure this is a bug is that this exception disappears when i instead write:

    public void someMethod() {
        String line = null;
        // and use it later..


sry, no time to dig for the reason myself.. np, i just work around this myself
but maybe it's a bug you'd like to fix ;)
