Radim found some quality issues like these:

• https://github.com/hibernate/hibernate-orm/blob/master/hibernate-testing/src/main/java/org/hibernate/testing/jta/JtaAwareConnectionProviderImpl.java#L155

I'd suggest to use Checstyle to avoid forgetting such experiments, like we do on Search here:

• https://github.com/hibernate/hibernate-search/blob/master/build-config/src/main/resources/checkstyle.xml#L153-L158

An alternative could be to use Forbidden APIs, which works on bytecode level so could also spot slightly more exotic syntax variations of the same problem.
