It may only be a small aspect of the language as a whole, but Java 1 did not have interfaces.
Java 2, inspired by Objective C protocols, was the first revision of the language that added interfaces.
For the rest of Java - besides interfaces - I have no comment about those origins.

My phase, "borrowed from standard C in the beginning," merely refers to the fact that Java is one of many "C-like" languages.
You are correct that Java was intended to be secure, but it's still capable of crashing when the program is complex enough. Computers still have memory addresses, and therefore handles or pointers, so in the end the issues are still there. Granted, the language makes it much more difficult to run in to handle or pointer errors.
I doubt there are many embedded systems (apart from DVD and Blu-ray players) that support Java code. At the very least, even a disc player has its low-level code written in some language more efficient than Java.
