AbstractBeanInfoFactory throws StringIndexOutOfBoundsException for short method names
-------------------------------------------------------------------------------------
Key: JBMICROCONT-229

Project: JBoss MicroContainer
Issue Type: Bug
Components: Container
Affects Versions: JBossMC-2.0.0.Beta7
Reporter: Brian Stansberry
Creating a bean of a type that contains a method whose name is 2 chars or less results in
the following:
java.lang.StringIndexOutOfBoundsException: String index out of range: -1

This is from attempt to create an instance of org.jgroups.JChannel, which includes a
method named up().
Problem is in AbstractBeanInfoFactory:
protected static String getUpperPropertyName(String name)
{
int start = 3;
if (name.startsWith("is"))
start = 2;
return name.substring(start);
}
A simple fix is to make the first line
int start = Math.min(3, name.length);
which will result in a return value of "" from name.substring(start) if name is
3 chars or less.
Alternatively, change getBeanProperties() to not call getUpperPropertyName() until it has
already determined the method is a getter or a setter.
