Bugs: ClassCastException in 1.1.0.M1 & no property found 1.1.0.BUILD-SNAPSHOT

Note: environment is Win7 64-bit, JDK 1.7.0_01 61-bit, Hibernate 3.6.7.Final & Oracle.

I've hit a bug similar to https://jira.springsource.org/browse/DATAJPA-45 with Spring Data JPA 1.1.0.M1. In DATAJPA-45, the ClassCastException has to do with ParameterizedTypeImpl, whereas the bug I see has to do with TypeVariableImpl.

Caused by: java.lang.ClassCastException: sun.reflect.generics.reflectiveObjects.TypeVariableImpl cannot be cast to java.lang.Class

After seeing that DATAJPA-45 was fixed in Spring Data Commons, I updated Spring Data JPA to version 1.1.0.BUILD-SNAPSHOT and got a different error:

Any ideas?

Hi Matthew,

make sure you pull the SD Commons 1.2.0.BUILD-SNAPSHOT as well (actually the pom.xml of SD JPA 1.1.0.M1 should do but I guess you've defined the dependency explicitly to SD Commons in your pom.xml). The latter error seems to be caused by a method declared not being a query method but rather a redeclaration of a CRUD method of some kind. Is there a chance you can show the repository declaration?

[matthewadams]

Nevermind. I had a slight inconsistency in my custom interface hierarchy. Fixed & now works with SD JPA 1.1.0.M1 & 1.1.0.BUILD-SNAPSHOT.

Glad it worked out for you!
