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.
