Manjot,

  This doesn't look like a motech issue, but rather something in NMS.  Is this from the 1.0.2 hotfix?  Did it start after the hotfix, or has it not started at all?  Also what has changed, was this from a new deployment or just a restart?  If it was a new deployment are all old versions of jars and bundles removed from the bundles dir before the deployment? Is there any other recent action that might help put the exception into context?

-Rob

According to Manjot they've been receiving these errors almost since the beginning.
But it doesn't seem to have any negative effect.

Hello

These warnings come from the BytecodeReadingParanamer. It is a library we use in MDS to read method's parameter names from the java bytecode. The BytecodeReadingParanamer relies on the debug information, which means that if the code has been compiled without the inclusion of debug information, the BytecodeReadingParanamer won't be able to read the method's parameter names (since they won't be included in the bytecode).

The generation of lookups will only be affected by this, if they have been defined without specifing lookup field names with @LookupField(name = "fieldName") annotation. If all lookup fields are marked with the annotation and have their names provided there, these warnings have no meaning.

Best regards,
Sebastian Brudzinski.
