Description

This issue only happens when running in weblogic:

After updating to Camel 2.12.2 the method createXMLStreamReader(InputStream in, Exchange exchange) in staxConverter throws an NPE because of the missing charsetName.
Comparing the class with the previous version I saw camel no longer falls back to the default charset.

As a workaround I set the property Exchange.CHARSET_NAME on explicitly -> still the same error.

Debugging the code I noticed that in org.apache.camel.impl.converter.BaseTypeConverterRegistry#convertTo line 98 the exchange is not passed to the converter so I can neither use an explicit nor an implicit charset.

Any workaround/fix would be greatly appreciated!
