Allocate memory

Tue Feb 12 20:54:00 GMT 2008

So Hans you think that allocating 128 MB is not a problem? Do you mean that the compiled application should allocate it automatically at runtime? 
The gcj version is 4.3 on 32-bit Windows XP. I am reading a number of text files and put their contents in a HashMap<String, String> (file name, text). 
In fact I need the text to be loaded in memory no matter in what way.
