Re: jdk1.4 problems.

Hi Stephen,

I haven't try soot-1.2.2 on JDK1.4, but tried soot-1.2.3, I did not find
the source of the problem, but here is a quick hacker to make it runable
on JDK1.4

In soot/jimple/toolkits/invoke/ClassHierarchyAnalysis.java
replace line 67 :
  Iterator methodsIt = c.getMethods().iterator();
by:
  Iterator methodsIt = c.getMethods().snapshotIterator();

It is not verified that this change won't affect others. (look at the
code, it is not supposed to be).

Cheers,
