Nullpointer exceptions in 64-bit versions

Recommended Posts

We have several customers reporting nullpointer exceptions on 64-bit windows machines. The exceptions appear at different places. In one case, this is in single-thread code that has not been changed for years. We cannot reproduce the problem here, nor has any OS X or 32-bit Windows user reported similar problems.

The code was compiled with Jet 8 MP 1 (before MP1, one customer reported crashes that were fixed after applying update 1). Can you please comment on whether there is any reason to believe that updating to Jet 9 might solve these issues? On your web site, you seem to strongly recommend the 32-bit version over the 63-bit version. Unfortunately, we need the 64-bit version to support large heap spaces. The Jet 9 description on your web site only mentions improvements and support for Java 7, but no bug fixes.

Any help or suggestions will be appreciated.

Excelsior JET 9 contains few bug fixes so I undoubtedly recommend you to recompile your application with latest JET.

Also note that we cannot investigate the problem until there is a way to reproduce it.
