1. Java (apple) plugins were not built into the browser; and it was not an internationally agreed standard between browser vendors. You needed to install a big plugin to make it work.
2. Due to the computing capacity of the average PC on those times, startup was slow and it consumed lots of memory.
3. Java applets could only be written in Java.
In comparison:
1. Webassembly is an standard, and its support is built into the browser.
2. Webassembly is very high performance, higher than what users come to accept as good (= Javascript under Google V8)
