> Stack overflow on cross imports in commons-jci-janino
> -----------------------------------------------------

> Key: JCI-53
> URL: https://issues.apache.org/jira/browse/JCI-53
> Project: Commons JCI
> Issue Type: Bug
> Components: compiler janino
> Affects Versions: 1.1
> Reporter: Edson Tirelli
> Assignee: Torsten Curdt
> Priority: Blocker
> Fix For: 1.1RC1
>
>
> A stack overflow occurs when trying to compile classes with cross references
> using commons-jci-janino, because an infinite recursion. The simple presence
> of cross reference import is enough to cause the problem.
> Example: the following classes will recreate the problem:
> package test;
> import static test.Func2.func2;
> public class Func1 {
> public static boolean func1() throws Exception {
> return true;
> }
> }
> package test;
> import static test.Func1.func1;
> public class Func2 {
> public static boolean func2() throws Exception {
> return true;
> }
> }
> The exception stack is:
> java.lang.StackOverflowError
