Indexing a field results in internal Exception

I have an application that I have been converting from JPA/MySQL to JDO/ObjectDB and I have hit a problem with indexing. An index on a String field is required to give good performance but if I add the @Index annotation to the field I eventually end up with an ObjectDB internal exception.  This is reproducible, as is the program running to completion (slowly) if I remove the @Index annotation.  Is there anything I can look for that might result in this exception? #1 2013-04-21 20:40 I have an application that I have been converting from JPA/MySQL to JDO/ObjectDB and I have hit a problem with in ...
