 The difference to similar projects is that not a complete VM with GC and memory management should be ported. It's more like a 1: 1 conversion. The generated WebAssembly code is similar in size to the original Java class files.

These features are already used by the trunk version of JWebAssembly.

 ### Java Limits
-In version 1 of WebAssembly you can only compile:
-* static methods
-* use the data types int, long float and double
-
-This is state of JWebAssembly 0.1. With version 0.2 you can use Objects via JavaScript polyfill.
+If you use it in the browser then only things can work that also work in the browser sandbox. This means file access or sockets will never work. Another problem are native parts of the Java VM. If there are no replacements via pure Java or JavaScript import then it will not work. [Contributions](https://github.com/i-net-software/JWebAssembly/blob/master/CONTRIBUTING.md) are wellcome.
