IIOException "tEXt chunk length is not proper" on opening png file

A DESCRIPTION OF THE PROBLEM :
When I try to read some png files, I get exception:

    at java.desktop/com.sun.imageio.plugins.png.PNGImageReader.readMetadata(PNGImageReader.java:891)
    at java.desktop/com.sun.imageio.plugins.png.PNGImageReader.getImageMetadata(PNGImageReader.java:1799)
    Caused by: javax.imageio.IIOException: tEXt chunk length is not proper
    at java.desktop/com.sun.imageio.plugins.png.PNGImageReader.parse_tEXt_chunk(PNGImageReader.java:575)
    at java.desktop/com.sun.imageio.plugins.png.PNGImageReader.readMetadata(PNGImageReader.java:847)
    .. 28 more
I think there are errors in file PNGImageReader. For example on line 574:
    if (textLength <= 0) {
        throw new IIOException("tEXt chunk length is not proper");
    }
Right condition is:
    if (textLength < 0) {
        throw new IIOException("tEXt chunk length is not proper");
    }

Similar problem is on a few other lines.
