maybe change pro to maven will easy add an action yaml to auto test every release will be a well way to aviod this error ?

I haven't encountered any issues when using it locally. Please ensure that your JDK version is 1.8.

wow! dude I can run it with Java 8! I thought it would take some time to get your response, but I didn't expect it to be so quick. Thank you for your answer. Does it mean the project doesn't support Java 11?

[qi4L]

In order to adapt to more extreme environments, I have lowered the compilation level to 1.6, but I'm not sure about the exceptions that may occur with JDK versions other than 1.6 and 1.8.

tha't all. thanks your work!
