Double 0.0 - why not?

Question

Hi all!
This is my first Post in here so hello to you all! :-)
I've got a simple question which took me about 3 hours of searching.
Im currently working on a project with about 25 Klasses (and counting).
I wanted to compile the code i've done so far on a different machine to see if it'll work fine there too (no problem on my developing machine).
After starting the compiler i get an Errormessage like this one:
++++++++++++++++++
Unexpected Signal : EXCEPTION_FLT_DIVIDE_BY_ZERO (0xc000008e) occurred at PC=0xB
CAAB8
Function=[Unknown.]
Library=(N/A)
NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.
Current Java thread:
Dynamic libraries:
0x00400000 - 0x00408000 C:\j2sdk1.4.2_01\bin\javac.exe
[...much more stuff here.....]
+++++++++++++++++++++++++
So i got no information where i can find the cause of this error. The only choice i had was to compile every file one by one till i tracket it down to one Class.
30Minutes later i found the position of the error: (removed code fragments one by one untill no compile error occured)
//"doubleString" is a String and gets checked against "" and null before...           
double doubleValue=new Double(doubleString).doubleValue();
//i tried also "doubleValue < 0.0"
if (doubleValue < 0) {
  //some stuff here
}after i changed the if clause to
if (doubleValue <0.01) {
}the above mentioned error was gone....
Now my question is what is so "bad" to check a double against 0.0? (Cause my other computer doesn't give me such an error)
And is it normal to get such an error during compilation? (without the compiler telling you where the error was found)
thanks in advance

strange! But thanks for the answers.
but now i got another compile error:
Unexpected Signal : EXCEPTION_FLT_STACK_CHECK (0xc0000092) occurred at PC=0xC1D1

I dont have a clue where to search for this one. Is it possible that my j2sdk1.4.2_01 installation on this machine is "broken"?
Never had errors like these before..
