Splunk Add-on for Java Management Extensions: How to resolve "Message: Invalid byte 1 of 1-byte UTF-8 sequence" error?

[Sampathu]

Hey, Our Splunk Add-on for Java Management Extensions (JMX) was working good. All of a sudden it stopped receiving data and I see the below error frequently.

Message: Invalid byte 1 of 1-byte UTF-8 sequence.
    at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:591)
    ... 20 more

Message: Invalid byte 1 of 1-byte UTF-8 sequence.
    at com.splunk.AtomObject.scan(Unknown Source)

Message: Invalid byte 1 of 1-byte UTF-8 sequence. : java.lang.RuntimeException: java.lang.RuntimeException: ParseError at [row,col]:[135,38]

I tried my ways, but no luck. Anyone has any idea about this error?

Note: Java_home is fine with jdk 1.8.

Finally found out myself. The "JMX" app was override by "Net-App" application. After disabling/removing the Net-App its working fine now. Not sure what's the in-depth issue between the both!!
