FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
in java.io.DataInputStream there is

private byte readBuffer[] = new byte[8];

...

    public final long readLong() throws IOException {
        readFully(readBuffer, 0, 8);
        return (((long)readBuffer[0] << 56) +
                ((long)(readBuffer[1] & 255) << 48) +
                ((long)(readBuffer[2] & 255) << 40) +
                ((long)(readBuffer[3] & 255) << 32) +
                ((long)(readBuffer[4] & 255) << 24) +
                ((readBuffer[5] & 255) << 16) +
                ((readBuffer[6] & 255) << 8) +
                ((readBuffer[7] & 255) << 0));
    }

This is not Thread safe since there is only one byte[] array (readBuffer) for the one method and it is not synchronized...



REPRODUCIBILITY :
This bug can be reproduced always.
