Raml validator throws error in javax.xml.validation.SchemaFactory.newSchema

While trying to check espn.raml, I got the following error. The same code works fine for gmail.raml . Why is this happening? For your reference, I included the results that I found in which banks the SchemaFactory is used.

$ find * .jar | xargs grep SchemaFactory.class Binary File

axiom_1.2.11.wso2v6.jar corresponds to a binary file

org.apache.openjpa_2.2.0.wso2v1.jar corresponds to the binary

solr_5.2.1.wso2v1.jar matches

This is the exception I get:

Caused by: java.lang.LinkageError: loader constraint violation: when resolving method "javax.xml.validation.SchemaFactory.newSchema(Ljavax/xml/transform/Source;)Ljavax/xml/validation/Schema;" the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) of the current class, org/raml/parser/rule/SchemaRule, and the class loader (instance of <bootloader>) for resolved class, javax/xml/validation/SchemaFactory, have different Class objects for the type m/Source;)Ljavax/xml/validation/Schema; used in the signature
