Re: [WebMacro-user] Rather strange error ..

[Bobby N. <bwn...@fe...>]

Endre,

I faced something just as screwy here at work. =20

We had some code that worked on every development machine in our shop;
intel/windows NT, intel/windows 2000, intel/RH Linux 7.2, intel/RH Linux
7.3, Sun Ultra I/Solaris 8, and 2 Sun Ultra II/Solaris 8s.  When we
moved that code into our staging/production environment, which is also
Sun Solaris 8 (unsure of the hardware model), it would bomb on us.  We
finally tracked the problem down to a call to a String objects'
getBytes() method. =20

The problem was in the JVM/Class library's implementation on that
particular combination of hardware/software.  Who knows if the os needs
patching or the JVM, but in the end we put a work around into our code
to avoid the call to getBytes. =20

I guess that's why Java's unofficial mantra is "write once, test
everywhere".
