[Bug]: StackOverflowError occurred in CtExecutableReference.getExecutableDeclaration #5584
Comments
|
When class C is not in the current project, stack overflow will occur in the following test example @Test()
void foo(){
Launcher launcher = new Launcher();
launcher.getEnvironment().setComplianceLevel(11);
launcher.getEnvironment().setAutoImports(true);
launcher.addInputResource(new VirtualFile("" +
"import com.C;\n" +
"import java.util.List;\n" +
"import java.util.function.BiFunction;\n" +
"\n" +
"public class A {\n" +
" public void test( List<? extends C> list, BiFunction<C, B, Boolean> func) {\n" +
" list.stream().forEach(c -> {\n" +
" func.apply(c, null);\n" +
" });\n" +
" }\n" +
"}\n" +
"class B{ }" +
""));
CtModel ctModel = launcher.buildModel();
List<CtExecutableReference> elements = ctModel.getElements(new TypeFilter<>(CtExecutableReference.class));
for (CtExecutableReference element : elements) {
try{
element.getExecutableDeclaration();
}catch(StackOverflowError e){
e.printStackTrace();
}
}

When class C is in the current project, the following test cases are normal @Test()
void foo(){
Launcher launcher = new Launcher();
launcher.getEnvironment().setComplianceLevel(11);
launcher.getEnvironment().setAutoImports(true);
launcher.addInputResource(new VirtualFile("" +
"import java.util.List;\n" +
"import java.util.function.BiFunction;\n" +
"\n" +
"public class A {\n" +
" public void test( List<? extends C> list, BiFunction<C, B, Boolean> func) {\n" +
" list.stream().forEach(c -> {\n" +
" func.apply(c, null);\n" +
" });\n" +
" }\n" +
"}\n" +
"class B{ }class C{}" +
""));
CtModel ctModel = launcher.buildModel();
List<CtExecutableReference> elements = ctModel.getElements(new TypeFilter<>(CtExecutableReference.class));
for (CtExecutableReference element : elements) {
try{
element.getExecutableDeclaration();
}catch(StackOverflowError e){
e.printStackTrace();
}
}

Can anyone answer me if it's actually a bug |
|
I mean, it is kind of a bug but not really. It only happens in noclasspath mode, because in there JDT's type inference gives up: The question is whether we want to try and make Spoon a bit smarter here and let it return from the call -- possibly returning garbage information. We could also make it return |

thanks, i suggest you can return |
