I accidentally replied off list. The reply was: Can you describe your runtime environment?
The description for this particular error says " this error is caught by the compiler; this error can only occur at run time if the definition of a class has incompatibly changed." What level of Java and UIMA etc., are you running? Is it possible you have some mixed levels? -Marshall On 6/6/2017 9:44 AM, Das, Tanmay wrote: > Hi > > When I try to run the following line of code(as given in the guide) : > jcs.serialize(cas, sw); > > It produces an error - > Exception in thread "main" java.lang.IllegalAccessError: tried to access > field org.apache.uima.cas.impl.CasSerializerSupport.COMPARATOR_SHORT_TYPENAME > from class org.apache.uima.json.JsonCasSerializer$JsonDocSerializer > at > org.apache.uima.json.JsonCasSerializer$JsonDocSerializer.collectUsedSubtypes(JsonCasSerializer.java:842) > at > org.apache.uima.json.JsonCasSerializer$JsonDocSerializer.serializeJsonLdContext(JsonCasSerializer.java:717) > at > org.apache.uima.json.JsonCasSerializer$JsonDocSerializer.writeFeatureStructures(JsonCasSerializer.java:532) > at > org.apache.uima.cas.impl.CasSerializerSupport$CasDocSerializer.serialize(CasSerializerSupport.java:439) > at > org.apache.uima.json.JsonCasSerializer.serialize(JsonCasSerializer.java:318) > at > org.apache.uima.json.JsonCasSerializer.serialize(JsonCasSerializer.java:299) > at > org.apache.uima.json.JsonCasSerializer.serialize(JsonCasSerializer.java:289) > > The definition of COMPARATOR_SHORT_TYPENAME in class CasSerializerSupport : > > final static Comparator<TypeImpl> COMPARATOR_SHORT_TYPENAME = new > Comparator<TypeImpl>() { > public int compare(TypeImpl object1, TypeImpl object2) { > return object1.getShortName().compareTo(object2.getShortName()); > } > }; > > Can anyone thank me with the problem. > > > Thanks > -TD > > This e-mail, including attachments, may include confidential and/or > proprietary information, and may be used only by the person or entity > to which it is addressed.
