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: 1.0
Reporter: Edson Tirelli
Assignee: Torsten Curdt
Priority: Blocker
Fix For: 1.1
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:
{code}
package test;
import static test.Func2.func2;
public class Func1 {
public static boolean func1() throws Exception {
return true;
}
}
{code}
{code}
package test;
import static test.Func1.func1;
public class Func2 {
public static boolean func2() throws Exception {
return true;
}
}
{code}
The exception stack is:
{code}
