[jira] [Commented] (NETBEANS-2221) ClassCastException when try to
open class from not opened module
[ https://issues.apache.org/jira/browse/NETBEANS-2221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16838628#comment-16838628 ]
Mark Herkrath commented on NETBEANS-2221:
-----------------------------------------
I am running into the same issue all the time and have done some analysis:
Code of {{org.netbeans.modules.java.source.builder.TreeFactory}}, where the ClassCastException happens:
{code:java}
public ExpressionTree Type(TypeMirror type) {
Type t = (Type) type;
JCExpression tp;
switch (type.getKind()) {
...
case ERROR:
tp = make.at(NOPOS).Ident(((ErrorType) type).tsym.name);
break;
default:
return make.at(NOPOS).Type((Type)type);
}
return tp.setType(t);
} {code}
The getKind() implementation of ClassType used to always return DECLARED. However since Java 11, the getKind() implementation of ClassType has been changed:
{code:java}
@DefinedBy(Api.LANGUAGE_MODEL)
public TypeKind getKind() {
tsym.apiComplete();
return tsym.kind == TYP ? TypeKind.DECLARED : TypeKind.ERROR;
} {code}
See [http://hg.openjdk.java.net/jdk/jdk/rev/cc2673fa8c20] due to [https://bugs.openjdk.java.net/browse/JDK-8187950]
As a result, the cast to ErrorType for getKind() == ERROR isn't always valid anymore. The strange thing is that I get the same error with Java 8u212 by Oracle (i.e. NB is running with that version and the Java version of my project is also set accordingly). Maybe it was back-ported but it's not clear to me if their com.sun.tools sources are publicly accessible somewhere. I don't see that change in the Java 8 release notes. Alternatively, NetBeans is using Java 11 for de-compilation for whatever reason. I have at least added it as a Java Platform.
