I just got a similar error report, ArrayIndexOutOfBoundsException within
StringBuilder.
Weird error, it is either a bug in StringBuilder or a VM/hardware glitch.
StringBuffer is appending "itemNotReady" to an empty StringBuffer, 4.1.1
(phone is samsung.GT-I9300.m0). It's all local variables, can't be
threading:

/** Concatenate a varargs list of parameters, but skipping any element that
matches ignore (unless ignore is null, then everything is shown) */
private String concatVarargs(Object[] args, Object ignore) {
StringBuilder s = new StringBuilder(100);
for (Object o : args) {
if ((ignore == null) || (o != ignore)) {
s.append((o != null ? o.toString() : "null")); <== error occurs
in s.append()
}
}
return s.toString();
}
I have the exact call in my log, it is concatVarags(["itemNotReady"],
null). Pretty simple
