java.lang.OutOfMemoryError: Java 在 apache 中读取图像时堆空间

Question

I am creating a pdf using Apache Pdfbox api. While trying to read image, getting Heap Space issue on the below code:

    PDXObjectImage ximage = null;

    InputStream is1 = new ClassPathResource(appProp.getProperty("fon1")).getInputStream();
    InputStream is2 = new ClassPathResource(appProp.getProperty("font2")).getInputStream();

    font = PDTrueTypeFont.loadTTF(doc,is1);
    font1 = PDTrueTypeFont.loadTTF(doc,is2);
    BufferedImage awtImage = ImageIO.read(new ClassPathResource(appProp.getProperty("Logo")).getInputStream());
    ximage = new PDPixelMap(doc, awtImage);
    float scale = 0.009f;

StackTrace:

java.lang.OutOfMemoryError: Java heap space] with root cause

Exception occurred while doing ImageIO.read, but not every-time. It's occurring randomly. Same is working fine while running the code in local machine but it's failing in Dev region.

Can somebody help me in resolving the issue.

Thanks,

I was able to resolve this issue after using the image of lesser size.
