As described in the linked issue, NullClassBytesTest fails due an
OutOfMemoryError produced on AIX when the test calls defineClass with a byte
array of size of 0. The native implementation of defineClass then calls malloc
with a size of 0. On AIX malloc(0) returns NULL, while on other

Please stop sending mails marked as urgent to a mailing list, you just make a

The need to round floating point numbers for commercial math (and the risk
involved in doing so) is nothing new, it predates the IEEE standard and should

Can you check JDK 8u? I would expect the exit code to be non-0 with that

Hello A.Z.
As Raffaello said, Java arithmetic does not have any more problem than
C/C++ when using IEEE 754. The "proof" of contrary is only an illusion
due to the rounding behavior of C/C++ output routines, as demonstrated
by Raffaello's code. Maybe some C/C++ code use Intel extended
Sorry, for some reason a line was missing in the C++ code
#include
using namespace std;
int main()
{
cout << "Program has started..." << endl;
double a = 0.1D;
double b = 0.1D;
double c = a*b;
double d = 0.01D;
cout << endl << "0.1D*0.1D " << (c == d ? "==" : "!=") <<
The new decimal literals have indeed the minimal length required to
recover the doubles closest to the true mathematical values.

Hi,
Java, as well as most implementations of most languages, including C and

1985. The standard specifies the formats, the outcome of operators and
