[英]Eclipse internal compiler error
在 Eclipse 中使用此代碼時:
import java.util.Arrays;
import java.util.HashSet;
import java.util.List;
import java.util.Set;
public class Test {
public static void main(String[] args) {
List<Object> objs = Arrays.asList(new Object(), new Object());
Set<String> s = objs.stream().collect(HashSet::new, HashSet::add, Object::toString);
System.out.println(s);
}
}
我得到:
Internal compiler error: java.lang.ArrayIndexOutOfBoundsException: 0 at
org.eclipse.jdt.internal.compiler.lookup.ConstraintExpressionFormula.reduceReferenceExpressionCompatibility(ConstraintExpressionFormula
.java:273)
我知道這是產生錯誤的這一行:
Set<String> s = objs.stream().collect(HashSet::new, HashSet::add, Object::toString);
不確定它是否相關,但我正在使用:
插件:Eclipse Java Development Tools Patch with Java 8 support (for Kepler SR2) and Eclipse Plug-in Development Environment Patch with Java 8 support (for Kepler SR2)
java.runtime.version=1.8.0-b132
這是屏幕截圖:
我知道 collect 方法不正確,但為什么我沒有編譯器錯誤告訴類似的內容:
- The method collect(Supplier<R>, BiConsumer<R,? super Object>, BiConsumer<R,R>) in the type Stream<Object> is not applicable for the arguments etc.
