Using maven dependencies:
<dependency>
<groupId>com.google.zxing</groupId>
<artifactId>core</artifactId>
<version>2.1</version>
</dependency>
<dependency>
<groupId>com.google.zxing</groupId>
<artifactId>javase</artifactId>
<version>2.1</version>
</dependency>

Fails only for certain numbers:
95
125
167
195
251
271
315
354

and so on, but can decode other numbers!

Also - tested using barcode scanner android app - it can decode 95 barcode
image produced by zxing. Perhaps bug is already fixed somewhere else?

You need PURE_BARCODE mode. In a pure image you are going to have false
positive detections of features easily, that don't happen in a photo. It's
optimized for photos.
