org.h2.test.unit.TestClassLoaderLeak
public class TestClassLoaderLeak extends org.h2.test.TestBase
Test that static references within the database engine don't reference the class itself. For example, there is a leak if a class contains a static reference to a stack trace. This was the case using the following declaration: static EOFException EOF = new EOFException(). The way to solve the problem is to not use such references, or to not fill in the stack trace (which indirectly references the class loader).
