TPM UDF getSystemEnvironment Error

Hi,

When trying to run this TPM function getSystemEnvironment(), I get the following Java Error:

Tracing for additional info -runtimeexception
 Thrown:
 com.sap.aii.mappingtool.tf7.MessageMappingException: Runtime exception when processing target-field mapping /ORDERS05/IDOC/EDI_DC40/SNDPRN; root message: Exception:[java.lang.StackOverflowError] in class com.sap.xi.B2B.MappingFunctions.UDFTPMPool method getSystemEnvironment[com.sap.aii.mappingtool.tf7.rt.Context@53caa681]

 at com.sap.aii.mappingtool.tf7.Transformer.start(Transformer.java:145) 

Has anyone encountered Stackoverflow error with this function?

As a function that has no input, do you know where should I review or check to fix this?

- Permissions?

- System Resources?

- Configurations?

- Packages needed to be installed?

Thanks
