Java isn't forward compatible?

• jfengel 3y ago
  Overwhelmingly it is, until it isn't. There are tiny gotchas, especially if you play with some of the murkier aspects, such as reflection or class loading. The more of someone else's code you use, the more likely one of them bumps into one of the gotchas. And that sets off a cascade of conflicting versions.
