fp.bugs 3325 java.lang.String : monitor InternSet, get(this) and put(this)

From: ###@###.###
This does not look like form output to me.


1) This is mainly a bug report, but I'm as well proposing a feature related to sa
me place
2) jdk-1.0
3) jdk-1.0
4) see below
5)-9) don't apply; I found bug in source code...

Bug report:
===========
The method "intern" in java.lang.String has two bugs

a) creation of InternSet is not monitored; a race condition could cause
two intern of the same string to use different hashtables

b) The sequence get(this) and put(this) is not monitored...


Feature request:
================
Also in java.lang.String
There is no way to check whether a string has been intern'ed without
automatically interning the string and making the hashtable grow. I
think a method similar to intern but returning null if the string wasn't
already intern'ed could allow a user in some cases to get benefits of
intern without paying the cost...
