| Version | Release Year | Key Feature | Why Choose 1.4.0? | |---------|--------------|-------------|--------------------| | Java 1.1 | 1997 | Inner classes, JAR | Too primitive. No Swing, no collections framework. | | Java 1.2 | 1998 | Swing, Collections | Missing NIO, logging, assertions. | | Java 1.4.0 | 2002 | NIO, logging, assertions | Sweet spot for early 2000s enterprise apps. | | Java 1.5 (5.0) | 2004 | Generics, enums, autoboxing | Major language change; often breaks 1.4 code. | | Java 1.6 (6) | 2006 | Scripting, JDBC 4.0 | More modern but still outdated. |

Rule of thumb: If your app runs on 1.4.0, it will also run on 1.4.2. But it may not run on 1.5+ due to generics and API removals.

Modern Linux kernels (5.x+) have removed some old system calls that Java 1.4.0’s HotSpot VM expects. You may see:

Error: could not find libjava.so
Error: could not find Java 2 Runtime Environment.

In this case, only a container or VM with an old kernel (2.6.x) will work. | Version | Release Year | Key Feature | Why Choose 1
