i have written a taglib class ;jboss is not calling release() (this method is in Tag class) which is a life cycle method in taglibs;

in other servers this method is calling implicitly?why jboss is not calling?

public class TagLib1 extends BodyTagSupport
{

public TagLib1()
{
name = null;
id = null;
border = null;
cellpadding = null;
cellspacing = null;
width = null;
addButtonName = null;
frmName = null;
NL = "\n";
elementsData = new StringBuffer();
}


public int doAfterBody()
throws JspException
{
return 0;
}

public int doEndTag()
throws JspException
{
blah ..blah..
}

public int doStartTag()
throws JspException
{
blah ..blah..
return 2;
}

public String getAddButtonName()
{
return addButtonName;
}

public String getBorder()
{
return border;
}

public String getCellpadding()
{
return cellpadding;
}

public String getCellspacing()
{
return cellspacing;
}

public StringBuffer getElementsData()
{
return elementsData;
}

public String getFrmName()
{
return frmName;
}

public String getId()
{
return id;
}

public String getName()
{
return name;
}

public String getWidth()
{
return width;
}

public void release()
{
name = null;
id = null;
border = null;
cellpadding = null;
cellspacing = null;
width = null;
addButtonName = null;
elementsData = new StringBuffer();
}

public void setAddButtonName(String addButtonName)
{
this.addButtonName = addButtonName;
}

public void setBorder(String border)
{
this.border = border;
}

public void setCellpadding(String cellpadding)
{
this.cellpadding = cellpadding;
}

public void setCellspacing(String cellspacing)
{
this.cellspacing = cellspacing;
}

public void setElementsData(StringBuffer elementsData)
{
this.elementsData = elementsData;
}

public void setFrmName(String frmName)
{
this.frmName = frmName;
}

public void setId(String id)
{
this.id = id;
}

public void setName(String name)
{
this.name = name;
}

public void setWidth(String width)
{
this.width = width;
}

private String name;
