Errors & memory

[Maxim Kizub]

Hello.

Two errors I've found.
1st, java.lang.Byte extends java.lang.Number.
2nd, java.io.File.mkdirs() has an error - NullPointerException in
line 203 (looks like toString() returns null).

Memory.
Oh... Kaffe takes about 4 times or more memory then Sun's JDK.
Is this a normal situation? My project requires 10 Mb for full
recompilation under jdk, and it throws OutOfMemoryError near the
start of compilation under kaffe (after it eats up 32 meg of memory)
:-(

Any recommendations?

PS Linux RedHat 5.1 (glibc)
