are using java 8? if you might want utilize latest javassist. @ to the lowest degree found when using version of 3.12 ga of javassist had problem. in maven pom:
<dependency> <groupid>org.javassist</groupid> <artifactid>javassist</artifactid> <version>3.18.2-ga</version> </dependency> hibernate jpa persistence java-8 persistence.xml
