Mibble 2.6 was release on 2005-12-10 containing this fix.

This was caused by the ObjectIdentifierValue.initialize() method throwing a validation exception for the 'test1Inc' symbol, thereby leaving the OID value uninitialized. Upon checking the value in other initialize() calls (for subsequent symbols) this lead to a null value being returned and erroneously used.

The fix for this was twofold. First, all the type and value initialization code has been fixed to properly handle null return values from previous initializations (i.e. typically a result of validation errors). Secondly, the ObjectIdentifierValue validation was changed to only report a warning on mismatching component names. Also the error message was improved to report the component name mismatch in a clearer form.

This has been fixed as of version 2.6.alpha3.

In the attached mib files the country field in the mib OID is inadvertantly renamed from gb(826) in test1 to gp(826) in test-inc.
Although in most cases Mibble correctly catches this, in this case it throws a Null Pointer Exception (apparently when trying to process the next line ("dcTeMibEntityObjects OBJECT IDENTIFIER ::= { test1 1 } -- tables")
