I had a similar problem an found two ways to fix it:
1.- Change jdk version. Apparently some code you are using needs a different jdk. In my case if I used jdk 1.3.1_01 it worked fine. If I used 1.3.1_10 it didn't.
2.- use the -noverify when invoking java

Hi there,

Can anyone help me with this as I am new to Ant build.
I am getting the java.lang.VerifyError when I try to run my build with a target environment.

I looked at a similar question earlier, and tried changing the JDK to a version 1.3.1_10, it did not work. The build.xml is as follows -

Thanks. Any help much appreciated.
