答案 0 :(得分：8)
增加堆空间。如果未指定更高的最大值，Java将使用64MByte堆内存。像这样开始你的应用程序：
java -Xmx128m MyClass
有128MByte。
看起来你在ant build中启动应用程序。我会分开建筑和执行。让ant创建一个批处理文件，用于启动应用程序。
现在您可能需要为ant本身增加堆空间。这是通过环境变量（为windows显示的解决方案）完成的：
set ANT_OPTS=-Xms512m -Xmx512m

您可以使用以下选项设置堆大小：
-Xms32m -Xmx128m
在此处查看VM选项：

但我会建议你检查消耗堆积的东西。您可以使用以下分析工具来执行此操作：
答案 2 :(得分：1)
其他答案并非完整而完整的答案。它们只是乐队助手。根本原因是因为您正在创建一个ImageIcon对象，该对象在后台创建这些线程。由于JPG腐败，我也遇到了这个问题。如果将内存大小增加到1 TB并不重要，如果用户上传损坏的图像，则可能会将所有内容都降低。相反，使用ImageIO并捕获创建周围的内存不足错误：
try { // catch OutOfMemoryError for corrupt JPG
BufferedImage inImage = ImageIO.read(new File(jpgAbsPath));
} catch (OutOfMemoryError oome) {
logger.log(Level.SEVERE, "Out of memory error when trying to read image " + jpgAbsPath +" .", oome);
return;
}

您的JVM的堆空间不足。尝试使用-Xmx切换到JVM以增加程序可用的堆空间量。
java -Xmx256m YourClassName
答案 4 :(得分：0)
默认情况下，如果没有modifiyin JVM start params，则会有128m的堆空间。
程序分配的内存大于128米。
您可以增加堆空间限制：
java -Xms<initial heap size> -Xmx<maximum heap size>
