Description

I have a simple class 'A' defined as follows:

======================================
public class A {
int p1;
String p2;
B b;
}
======================================

While I execute the following instructions:
ToStringBuilder builder = new ReflectionToStringBuilder(a);
System.out.println(builder.toString());

The output is:
A@3ea981ca[p1=0,p2=<null>,b=B@1ee7b241]
that's normal, without recursion

So, I defined my own style, for recursive toString-ing display:

======================================
class MyStyle extends ToStringStyle {
private final static ToStringStyle instance = new MyStyle();

public MyStyle()

{ setArrayContentDetail(true); setUseShortClassName(true); setUseClassName(true); setUseIdentityHashCode(true); setFieldSeparator(", "); }

public static ToStringStyle getInstance()

{ return instance; }

;

@Override
public void appendDetail(final StringBuffer buffer, final String fieldName, final Object value) {
if (!value.getClass().getName().startsWith("java"))

{ buffer.append(ReflectionToStringBuilder.toString(value, instance)); }

else

{ super.appendDetail(buffer, fieldName, value); }

}

@Override
public void appendDetail(final StringBuffer buffer, final String fieldName, final Collection value)

{ appendDetail(buffer, fieldName, value.toArray()); }

}
======================================

When I use my custom MyStyle:
String s = ReflectionToStringBuilder.toString(a, MyStyle.getInstance());
System.out.println(s);

The output is:
A@3ea981ca[p1=0, p2=<null>, b=byte@1ee7b241[p4=234]]

So, the name of the class 'B' is not displayed.
I expected something like: b=B@1ee7b241[p4=234]

Instead, the name of the class 'B' is replaced with 'byte'.
I don't know why.
