Parametrized methods with @ Buiilder fail to compile in javac if builderMethodName is set. Eclipse is fine.

/**
* Without builder method name.
*
* Compiles and runs in eclipse and javac
*
* @ param <COMPARABLE> the generic type
* @ param comparableSet the comparable set
* @ return the list
*/
@ Builder(builderClassName = "FirstListOfSortedSetsBuilder")
static <COMPARABLE extends Comparable<?>> List<SortedSet<COMPARABLE>> withoutBuilderMethodName(
SortedSet<COMPARABLE> sortedSet) {
return ImmutableList.of(sortedSet);
}

/**

 * Compiles and runs in eclipse.
 *
 * DOES NOT COMPILE IN JAVAC:
 * error: incompatible types: List<SortedSet<COMPARABLE﹟1>> cannot be converted to  List<SortedSet<COMPARABLE﹟2>>
 *
 * @ param <COMPARABLE> the generic type
 * @ param comparableSet the comparable set
 * @ return the list
 */
@ Builder(builderClassName = "SecondListOfSortedSetsBuilder", builderMethodName = "newListOfSortedSetsBuilder")
static <COMPARABLE extends Comparable<?>> List<SortedSet<COMPARABLE>> withBuilderMethodName(
        SortedSet<COMPARABLE> sortedSet) {
    return ImmutableList.of(sortedSet);
}

It also fails on ctors.

Well spotted, and thanks a lot for your in-depth test case on the forums.

The bug has been fixed and will be in the next release.
