public void resetCaches()

Overrides default org.hibernate.bytecode.spi.BytecodeProvider.resetCaches.

Doc from org.hibernate.bytecode.spi.BytecodeProvider.resetCaches.

Some BytecodeProvider implementations will have classloader specific caching. These caches are useful at runtime but need to be reset at least on SessionFactory shutdown to prevent leaking the deployment classloader. Since the BytecodeProvider is static these caches are potentially shared across multiple deployments; in this case we'll clear all caches which might show as a small, temporary performance degradation on the SessionFactory instances which haven't been closed. This limitation will be removed in the future, when these providers will no longer be static.
