Java Sucks (So C# Didn't Have To)
summary
Java explains why generics use type erasure (JSR-14 chose backward compatibility over VM changes), so runtime type info is gone and libraries must pass type tokens; lambdas clash with checked exceptions, forcing try/catch workarounds or rethrowing as runtime exceptions; virtual threads improve throughput but suffer thread pinning (Netflix shows requests drop to zero in worst cases) until later fixes; Project Valhalla promises value types and null-restricted types but spends 10+ years unblocking deep VM and type-system debt.
