  java full version "1.4.0-beta2-b65"

  JDK 1.4.0beta2
  java full version "1.4.0-beta2-b77"

  JDK 1.4.0beta3cap build 82
  java full version "1.4.0-beta3-b82"

Does this problem occur on J2SE 1.3?  Yes / No (pick one)
  No. Works fine on 1.3.1.

Operating System Configuration Information (be specific):
  Windows 2000 SP2. OCR-A font installed.

Hardware Configuration Information (be specific):
  Pentium III 800MHz, 256MB RAM, Geforce 256 graphics card. Reported for other
  configurations as well.

Bug Description:
  Cap member's customer reported that their application crashes if certain 
  fonts are installed. They investigated this issue and produced a testcase
  which should offer some insight.

  Installing certain other fonts triggers this behaviour as well. More 
  information can be provided if required.


Steps to Reproduce (be specific):
  1) Install the attached font(Ocr-a.ttf).
  2) Run the attached test-case(FontTest.java).

An sample HotSpot error log(hs_err_pid1780.log) is attached.

EVALUATION This crash can be observed on solaris as well as windows and is deep in the hinting code. It makes sense that this wasn't reproducible on 1.3 as the hinting support code is all new in 1.4. ###@###.### 2001-10-12 ============================ The font shows severe problems with font verification tools on both Windows and the Macintosh. The "prep" (PREPROGRAM) table has some indices out of range. This seems to cause failures in the Java rasterizer. It needs to be investigated if the Java rasterizer can somehow work around such incorrectly hinted fonts. The font works in Windows as the windows trutetype rasterizer is able to work around this problem. ###@###.### 2001-10-15 Upon further evaluation it seems there are some other problems in the font too. ###@###.### 2001-10-15 Crash is in fnt_MIRP. fnt_MIRP should not be called in the first place. This was caused by wrong func tion being called because the stack containing the function ID was corrupted. T his corruption was due to a call to WS with index beyond the alotted storage spa ce (maxp->maxStorage). To work around this problem, we must increase allocated space for storage. ###@###.### 2002-10-07 =================================
