Crash when compiling Cayenne in the QualitasCorpus

Issue #253 resolved
Sebastian Hjelm created an issue

ExtendJ 8.0.1-220-gfec29ac Java SE 8

When compiling the Cayenne project from the QualitasCorpus ExtendJ crashes with a StackOverflowError. Increasing the stacksize does not seem to resolve the problem. In the test below I ran it with 1gb och stack space. Looking at the shape of the stacktrace there seems to be an infinite recursive loop in the compiler. The stacktrace is attached in the issue.

I compiled using: java -Xss1024m -Xms4096m -jar extendj.jar @systems_10\cayenne-3.0.1

    Here is a smaller test case that seems to trigger the same stack overflow:

    import java.util.*;
    public class Test {
      public static void main(String[] args) {
        setParams(Collections.singletonMap("a", null));
      static void setParams(Map<String, ?>... params) {

    This bug only affected the Java 8 version. The Java 7 version of ExtendJ did not have this issue.

    Fix stack overflow in method applicability testing

    Stack overflow was caused by circularity in method applicability testing. This has been solved in the same way as previously, by using a temporary bound access to lock a method access during applicability testing.
