After correctly creating a BPEL process, when I go to create a new process, the creation does not start, giving me this error:
java.lang.LinkageError: loader constraint violation for class org.eclipse.bpel.model.impl.BPELExtensibleElementImpl: when selecting overriding method 'javax.wsdl.extensions.ExtensibilityElement org.eclipse.bpel.model.impl.BPELExtensibleElementImpl.removeExtensibilityElement(javax.wsdl.extensions.ExtensibilityElement)' the class loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @817cd05 of the selected method's type org.eclipse.bpel.model.impl.BPELExtensibleElementImpl, and the class loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @6954431a for its super type org.eclipse.wst.wsdl.internal.impl.ExtensibleElementImpl have different Class objects for the type javax.wsdl.extensions.ExtensibilityElement used in the signature (org.eclipse.bpel.model.impl.BPELExtensibleElementImpl is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @817cd05, parent loader 'platform'; org.eclipse.wst.wsdl.internal.impl.ExtensibleElementImpl is in unnamed module of loader org.eclipse.osgi.internal.loader.EquinoxClassLoader @6954431a, parent loader 'platform')
