Java 语言断言错误

Question

我在使用 Java Web Start 运行 java 应用程序时遇到此错误。尽管应用程序在 Eclipse 中运行得非常好，并且应用程序也在 Java Web Start 中正确加载。该代码尝试打开文件选择器，但无法执行此操作。

Answer 1

好的，我刚刚找到了我自己问题的答案。我已禁用 JNLP 文件中的断言，代码开始工作得很好。

我变了

<j2se version="1.5+" java-vm-args="-esa -Xnoclassgc"/>

到

<j2se version="1.5+" java-vm-args="-dsa -Xnoclassgc"/>

希望这对其他人也有帮助。
