      Description

      FULL PRODUCT VERSION :
      java version "1.7.0_45"
      Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
      Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

      java version "1.8.0-ea"
      Java(TM) SE Runtime Environment (build 1.8.0-ea-b121)
      Java HotSpot(TM) 64-Bit Server VM (build 25.0-b63, mixed mode)

      A DESCRIPTION OF THE PROBLEM :
      A user reported that a certain online video causes our application to fail. Upon investigation it seems that adding a string containing the title of the video to a JTable causes an ArrayIndexOutOfBoundsException somewhere in the rendering code.

      Specifically, this issue occurs if a word containing a certain kind of string is truncated to fit in the table (with "..."). (To observe this, try adding a long ASCII-only word at the beginning of the string and then resizing the frame manually.)

      However, there is a catch. Everything works correctly if the "Arial Unicode MS" font is merely *installed* on the computer (*no matter which font is actually set* using setFont(...)). This font comes with Microsoft Office and is not included in Windows by default.

      We tested this extensively on both Java 7u45 and Java 8 (b121) on Windows 7 and 8. This was also reproduced on Windows XP and Ubuntu.

      ADDITIONAL REGRESSION INFORMATION:
      The test case additionally causes a JVM crash in 7u25, but that is already fixed in 7u45 and 8 (b121).

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      - Run the test case on a newly installed Windows 7 system without any extra programs installed. Observe behavior. (Exception occurs.)
      - Install the Arial Unicode font, either by installing Microsoft Office or by copying the file from another system.
      - Run the test case again and observe behavior. (No exceptions occur.)

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Frame correctly rendered and no exceptions, no matter which fonts are installed or set.
      ACTUAL -
      stdout: Arial Unicode is not installed
      stdout: Testing with font: java.awt.Font[family=Kartika,name=Kartika,style=plain,size=12]
