AutoValue does not handle names beginning with double capitals well

[alpeshvas]

package com.alpesh.Test
 public abstract class Test implements ITest {

        public static Builder builder() {
		return new AutoValue_Test.Builder();
	}

	AutoValue.Builder
	public abstract static class Builder {
		public abstract Builder xIdentityContext(String xIdentityContext);
		public abstract TnCredentials build();
	}

}


public interface ITest {
	String getApiKey();
	boolean isDebug();
	String getUrl();
	String getXIdentityContext();
}

Consider the above code at first. Note the method name in ITest interface for method getXIdentityContext

Build failed with

Method does not correspond to a property of  com.alpesh.Test
   	public abstract Builder xIdentityContext(String xIdentityContext);

Now, comes the interesting part, when changed that method name in ITest Interface with getXidentityContext ( I -> i ) and did same in AutoValue.Builder( I -> i ). Build succeeded. Have any one experienced this before . Is Autovalue unable to detect property when there is two Capital letters at the beginnig ?

I believe AutoValue uses the JavaBeans™ conventions, and getXIdentityContext following those rules is a getter for a XIdentityContext property. See https://docs.oracle.com/javase/8/docs/api/java/beans/Introspector.html#decapitalize-java.lang.String- which explains this special-case.

Thanks @tbroyer

We recognize that the JavaBeans behaviour is a bit of a misfeature, and I added code (a year ago today) that covers the mirror case, where the getter is xIdentityContext() and the setter is setXIdentityContext(x). We could imagine doing the same thing for this case.
