Error:java: java.lang.StackOverflowError

I've never had issues running my program before and I'm not sure what could be the cause of this.

My system has 6 gb of ram available with 1gb allocated to the JVM. When running a previous version, I have no issues.

If anyone could help me troubleshoot what the cause of this might be, I would appreciate it.

Sorry about the question, I literally copy/pasted the entire source to a different module with the same exact settings and it's working good as new. If anyone has any explanation as to why this is the case, please, let me know.

Answer 1

Firstly, you don't run your program, you compile it. It is the java compiler that dies of stack overflow.

Clearly, your source code is too complicated for the java compiler to deal with. To run the java compiler with more stack space

javac -J-Xss4m ....

If you don't run javac directly, but through some "build tool", this is the time to find out how good it is. A good build tool, while providing reasonable defaults, should let you customize your final compilation command line at will.
