The following errors appear while executing a job on ESB runtime, though the job ran in Studio successfully:
Caused by: java.lang.Error: java.lang.LinkageError: loader constraint violation: when resolving method "javax.xml.validation.Validator.setErrorHandler(Lorg/xml/sax/ErrorHandler;)V" the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) of the current class, esb_import/createcustomerjob_0_1/CreateCustomerJob, and the class loader (instance of <bootloader>) for resolved class, javax/xml/validation/Validator, have different Class objects for the type org/xml/sax/ErrorHandler used in the signature
You need to figure out the violation jar which contains javax/xml/validation/Validator in the output .kar file, then remove the jar file from the bundle's MANIFEST.MF file Bundle-ClassPath.
Note: Be careful about the 70 byte limit while modifying the MANIFEST.MF Bundle-ClassPath.
