Error log
==========
invalid inferred types for M#1,I#4; actual arguments do not conforms to inferred formal arguments
                RowFilter.orFilter(myList);
                                  ^
    required: Iterable<? extends RowFilter<? super Object,? super Object>>
    found: List<RowFilter<? super TableModel,Object>>
  where M#1,M#2,I#3,I#4 are type-variables:
    M#1 extends Object declared in method <M#2,I#3>orFilter(Iterable<? extends RowFilter<? super M#2,? super I#3>>)
    M#2 extends Object declared in method <M#2,I#3>orFilter(Iterable<? extends RowFilter<? super M#2,? super I#3>>)
    I#3 extends Object declared in method <M#2,I#3>orFilter(Iterable<? extends RowFilter<? super M#2,? super I#3>>)
    I#4 extends Object declared in method <M#2,I#3>orFilter(Iterable<? extends RowFilter<? super M#2,? super I#3>>)
Note: UnitTest.java uses unchecked or unsafe operations.

Please find the attached log file for more details on issue.

EVALUATION Here is the note from the compiler team: The simplest way to fix the test is to replace the following line RowFilter<? super TableModel,Object> orFilter = RowFilter.orFilter(myList); with RowFilter<? super TableModel,Object> orFilter = RowFilter.<TableModel, Object>orFilter(myList);
