Very different VMs

• GNU Classpath is used by very diverse VMs

  • Very different (sometimes conflicting) design goals
  • Extremes: gcj ↔ Jaos, JNode OS ↔ IKVM.NET
    • gcj: Java ≃ C++
    • Jaos, JNode OS: Cannot support any C code, no POSIX
    • IKVM.NET: Build to be integrated into .NET platform/libraries
