 * @summary converted from VM Testbase nsk/jdi/Method/isBridge/isbridge001.
 * VM Testbase keywords: [quick, jpda, jdi]
 * VM Testbase readme:
 * DESCRIPTION
 *     This test exercises the JDI method
 *         com.sun.jdi.Method.isBridge()
 *     It verifies that 'bridge methods' generated during translation of
 *     generic classes are determinated properly by the method.
 *     Here are the rules from the spec "Adding Generics to the Java
 *     Programming Language: Public Draft Specification, Version 2.0"
 *     followed by the test:
 *         6.2 Translation of Methods
 *         ...
 *         - If C.m is directly overridden by a method D.m in D, and the
 *           erasure of the return type or argument types of D.m differs from
 *           the erasure of the corresponding types in C.m, a bridge method
 *           needs to be generated.
 *         - A bridge method also needs to be generated if C.m is not
 *           directly overridden in D, unless C.m is abstract.
 *     The test works as follows. Debuggee contains several dummy superclasses
 *     and subclasses. Some of their methods fall under the rules above.
 *     Debugger verifies that the JDI Method.isBridge() returns true for all
 *     generated bridge methods and false for the non-bridge ones.
 *     The list of the class methods is obtained through the JDI
 *     ReferenceType.methods() which must return each method declared directly
 *     in this type including any synthetic methods created by the compiler.
 * COMMENTS
 *      Fixed bug 5083386: isbridge001c and isbridge001cc classes and
 *      the corresponding tests were removed
