Application Crashes After Upgrading

Aspose.Words Product Family
1

Is there a new minimum version of GSON for the Java version of Words?

I upgraded to Java 19.9 (from 19.3) and and am now getting an exception out of GSON:

java.lang.NoSuchFieldException: ASCII

It appears to occur in fromJSON applied to the following class:

com.aspose.words.internal.zz5F$zzZ

I also use GSON and currently have it pinned to 2.8.4.

Do I need to upgrade my version of GSON?

This may be an unresolved name clash between a new class in the Java library and a class name in my code. Any chance you can tell me (privately if need be) the name of the class zz5F$zzZ maps to?

Whatever change is causing this, it occured in 19.6. 19.5 works fine in my application.

It appears the issue was related to removing or renaming a field “ASCII” in classes related to Field or List. I was able to work around the change by marking the fields in my class which depended on those classes as transient (they aren’t involved in deserialization anyway).

Here is a reproducer:


import com.google.gson.Gson;

@Test
public void deserializationTest() throws Exception {
	Gson gson = new Gson();
	MyClass m = gson.fromJson("{\"myInteger\":1}", MyClass.class);
	assertEquals(1, m.myInteger);
}

class MyClass {

	int myInteger;
	com.aspose.words.Field myField;
	com.aspose.words.List myList;
	
}

throws:
java.lang.AssertionError: AssertionError (GSON 2.8.5): java.lang.NoSuchFieldException: ASCII

I was able to resolve the issue in my context by marking the aspose fields as transient. That is:

@Test
public void deserializationTest() throws Exception {
	Gson gson = new Gson();
	MyClass m = gson.fromJson("{\"myInteger\":1}", MyClass.class);
	assertEquals(1, m.myInteger);
}

class MyClass {

	int myInteger;
	transient com.aspose.words.Field myField;
	transient com.aspose.words.List myList;

}

works as expected (no exception).
