[kaffe] Hashtable.get() bug

[Alexander Popov]

Opppsss, sorry...

I was pretty busy - I guess I should have had my time on the example 
code - sorry.
I still pretend that the bug is there though. I'll write a good example.

...just to illustrate the problem, see this ( it's where it crushes our 
service framework ) :

<cut>

/**
   * Reads the current storage size.
   */
   private void init() throws IOException {
	System.out.println("--404: FileSystemImpl - init 1");
	System.out.println("--404: FileSystemImpl - SIZE : " + SIZE);

	// 404 - Kaffe workarround

    System.out.println("--404: FileSystemImpl - props : " + ( props == 
null ) );

   System.out.println("--404: FileSystemImpl - +1 " );

	byte[] bytes = (byte[]) props.get(SIZE);

	System.out.println("--404: FileSystemImpl - init 2");
	
	if(bytes != null) currentlyUsedStorage = toLong(bytes);

	// currentlyUsedStorage = 729200;

	// 404 ^

	System.out.println("--404: FileSystemImpl - init 3");
   }

<cut>

props is Xproperties which extends Properties...


And here is the output from the framework start process:

<cut>

--404: FileSystemImpl - 3
--404: FileSystemImpl - 4
--404: FileSystemImpl - init 1

--404: FileSystemImpl - props : false

comment: see this - props is not null here (check the source above )- I 
checked that before submitting the bug report...

--404: FileSystemImpl - +1
