Re: NullPointerException (2nd)

["Uwe Dolinsky" <u.dolinsky@iname.com>]

Sorry, I forgot to post the initial reply to the mailing list.
I'm using Soot 2.1.0 and jdk1.3.

The problem seems to be the CLASSPATH, which on my machine
includes the J2ME classes (CLDC and MIDP) required for my projects:

c:/java/soot-2.1.0/classes;.;C:\java\jasminclasses-sable-1.2.7.jar;
c:/java/j2me_cldc/api/classes.zip;c:/java/midp2.0fcs/build/win32/kvm/classes.zip;
 
When I remove the J2ME classes from CLASSPATH, Soot works fine on that simple
example I posted earlier, but rightly complains on files that use those classes;

Will there be a fix for this
