CIL error with missing end tag

Hi

I created some new objects and a CIL compile gives me the folling error:

CIL generation: Name cannot begin with the '<' character, hexadecimal value 0x3C. Line 17859, position 260.

Having a look in the XML I can see the following:

<Class name='AMVMsgQueueInCALLOFFPackingSlipLineHist' type='table' isMap='false' isScsc='true' id='105235' extends='105241' extendsName='AMVMsgQueueInForecastPackingSlipLineHist' isAbstract='false' isFinal='false' isInterface='false' isKernelClass='false'    <Interfaces>
    </Interfaces>

As you see there is the Endtag "<class " missing.

How can I resolve that Issue and why does it appear
