Java2D is still crashing with JDK-1.2fcs-F on Solaris-x86 (test machine: Dino)
Java2D crashes regardless of whether JIT is turned ON or OFF. So, tried both
java Java2Demo and java -Djava.compiler= Java2Demo

==================================


phil.race@eng 1998-09-11

There have been various bugs which crashed the demo on x86.

The description in this bug report characterises several which are known
and fixed

Specifically :-

-------

Exception occurred during event dispatching:
java.lang.NullPointerException
        at sun.awt.Albert.TBezierList.mergeArray(Compiled Code)

is the fixed JIT bug, id: 4149943, and its dup 4157675

-------------

Description: Java2D is still crashing on x86 with the C-bld. I have some info o
n one of the seg-vios. This time, it crashed when I attempted to go to the Colo
rs tab.

is the fixed CMM bug id 4099441, and the dup 4120723

---------------

However there remains at least one bug, which is reproducible in most
parts of the demo because it always shows up as a SEGV in the native
code which performs the pathfilling calculations.

Its a very hard and immediate SEGV which does not print out a Java stack
trace.

The way to confirm its the same crash is to obtain a core file and
run dbx, and note the stack trace.

This crash manifests itself as a runaway recursion of the function
processToRunsArc3, invoked when filling a cubic curve path.

The core dump would show a stack backtrace something like this :-

  [1] processToRunsArc3(0x841f170, 0xb40841f1, 0xf3b40841), at 0xdb9b38f3

A partial explanation of why this happens is that the floating point
values passed into the processToRunsArc3 method are badly corrupted.
The values that are printed out, if you add statements show that NaN, or -NaN
is passed in as floating point arguments.
So it recurses trying to split the path into smaller parts.

The cause may be a memory smash or some form of floating point problem.

If its a memory smash, its not clear where, since although there
are short/long casts, those should cause a problem on wintel as well
as solaris x86.
There's no (other) platform specific code in the affected library.

The non-optimised version does not crash (although in a possibly related
problem it does slowly leak memory).

This may mean that in the case of debug vs optimised versions
* some structures have moved and aren't getting smashed in the debug version
* there is a compiler optimiser bug in the optimised version
* some fp calculations are now being optimised and may now cause underflows/
  overflows/get different results, whereas they didn't in the debug version.

  - If I enable fp traps and catch fpe's I do see more of them in the
 optimised version. This could account for a SPARC/Intel difference as
 the Sun C compiler would invoke different fp h/w routines on the different
 architectures.
 However I can't locate anything which indicates that -xO2 optimises FP.

Also it takes a large test program like Java2D to reproduce the problem,
which lends itself to a memory smash theory.

The problem is harder to reproduce on some machines than others.
Catching the problem running under dbx has proved tricky.
Print statements are the only thing that has shown up anything
The RTC memory leak facilities of the debuggger aren't supported on x86.

By the time we crash its a long time after the problem was introduced.
Having to work backwards a long way to try to find this cause.

The bug is still reproducible in the engineering nightly build from
10-sep-98
