String oldTab = driver.getWindowHandle();
//clicking link to open new window
if(driver.findElement(By.xpath("element")).isDisplayed())
{ 
   Actions aBuilder = new Actions(driver);                                                            aBuilder.keyDown(Keys.SHIFT).click(link).perform();
   ArrayList<String> newTab = new ArrayList<String>(driver.getWindowHandles());
   newTab.remove(oldTab);
   driver.switchTo().window(newTab.get(0));
   //peform action
   driver.close();
   driver.switchTo().window(oldTab);
}
String oldTab1 = driver.getWindowHandle();
driver.navigate().refresh();
//Clicking link to open in new Window
if(driver.findElement(By.xpath("element")).isDisplayed())
{ 
   Actions aBuilder1 = new Actions(driver);
   aBuilder1.keyDown(Keys.SHIFT).click(link1).perform();
   ArrayList<String> newTab1 = new ArrayList<String>(driver.getWindowHandles());
   newTab1.remove(oldTab1);
   driver.switchTo().window(newTab1.get(0));
   //perform action
   driver.close();
   driver.switchTo().window(oldTab1);
}  

Answer 1

keyDown method presses the key but doesn't release it.

Try to replace

aBuilder1.keyDown(Keys.SHIFT).click(link1).perform();

with

aBuilder1.keyDown(Keys.SHIFT).click(link1).perform();
aBuilder1.keyUp(Keys.SHIFT).perform();
