I have bootstrapped Vector, Hashtable and HashMap. The only diference was that
the initialCapacity became equal 1 (istead of 10) in implementation of empty
constructors for these classes. Affter bootstrapping those 3 classes
NullPointerException started to accure in SecureRandom!
SecureRandom.getPrngAlgorithm() finds property which key starts
with "SecureRandom." and returns the rest of the key (String) after the dot in
it. BUT there are several property keys, that correspond to the algoritm name
(that has to be found) because an algorithm has several values. All keys,
assosiated with "SecureRandom" algorithm start with "SecureRandom.",
SecureRandom.getPrngAlgorithm() find the key, that has algorithm's
implementation classname in it's value.
For example:
there are properties
"SecureRandom.SHA1PRNG" -> "sun.security.provider.SecureRandom"
"SecureRandom.SHA1PRNG ImplementedIn" -> "Software"
When getPrngAlgorithm() finds "SecureRandom.SHA1PRNG", everything is fine, BUT
when it first finds "SecureRandom.SHA1PRNG ImplementedIn", it returns
String "SHA1PRNG ImplementedIn" instead of "SHA1PRNG" and this is the reason
why NullPoiterException occurs after using the result of this method.

This reveals after bootstrapping of Vector because the order of the keys in
implementations of Hash is sensitive to initialCapacity of Vector.
But probably this can be reproduced in other ways also.
