> Hi team!
> I have 2 classes:
> * Invoice extends AbstractInvoice
> * Quote extends AbstractInvoice
> And I try to run
> {code:java}
> AbstractInvoice abstractInvoice = new Invoice()
> if (abstractInvoice.newRecord || abstractInvoice instanceof Quote) {
> abstractInvoice.setContact(new Contact())
> } {code}
> I get "Exception in thread "main"
> org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast
> object 'groov.Invoice@3f2a3a5' with class 'groov.Invoice' to class
> 'groov.Quote'"
>
> I investigated build files and I saw this:
> {code:java}
> Invoice abstractInvoice = new Invoice();
> Object var10000;
> if (((Invoice)abstractInvoice).isNewRecord() || abstractInvoice instanceof
> Quote) {
> ((Quote)ScriptBytecodeAdapter.castToType(abstractInvoice,
> Quote.class)).setContact(new Contact());
> var10000 = null;
> } {code}
> Groovy sees 'abstractInvoice instanceof Quote' and tries to cast Class to
> Quote. But It forgets about || condition.
> In our project we use 2.5.15 version and we upgrading it to 4.0.2 version.
> After investigation I found that this behavior appeared in 3.0.11 version.
> 3.0.10 and older work correct.
> If I use Main Java class it works correct as well.
> I localized issue here (minimum classes and dependancies):
> [^ErrorWithCast.zip]
> Part from our project(more inheritance): [^TestJavaGroovyGradleProject
> 2.zip][^TestJavaGroovyGradleProject.zip]
