com.sun.tools.javac.tree.JCTree$JCTypeApply cannot be cast to com.sun.tools.javac.tree.JCTree$JCArrayTypeTree #457

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
This code: 

{{{
@ToString
final class Foo {
    private transient String format;
    private transient List<Object> arguments;
}
}}}

Leads to (with OpenJDK 7):

Can you specify the exact version number of javac?

$ java -version

This is not reproducible for us (but we don't have an openjdk 1.7.0_12-ea lying 
around). Looking at line 207, this would happen if you have a method named 
.getArguments() which returns an array. We fixed that in edge, can you download 
that and see if this problem still occurs for you?

edge is at:

NB: Also, just so you know, if you have a field named arguments and a method 
named .getArguments(), then toString() and equals() and hashCode() will all use 
.getArguments() instead, and thus also whatever type that method returns. Just 
FYI. You can override this behaviour with an argument on @ToString and company.

I can replicate it here with ToString

I'm using jdk 7u17 from sun/oracle though

java version "1.7.0_17"
Java(TM) SE Runtime Environment (build 1.7.0_17-b02)
Java HotSpot(TM) Client VM (build 23.7-b01, mixed mode, sharing)

Could this be a JDK 64bit bug?
