Options

[multiple changes] 

2002-02-14  Mark Wielaard  <mark@klomp.org>

    * java/math/BigInteger.java: import gnu.java.math.MPN not the whole
    package as a workaround for gcj 3.0.x

2002-02-14  Mark Wielaard <mark@klomp.org>

    * java/security/BasicPermission.java: extends with fully qualified
    classname as workaround for gcj 3.0.4.

2002-02-14  Eric Blake  <ebb9@email.byu.edu>

    * java/net/DatagramSocketImpl.java (setOption, getOption): Work
    around gcj bug of wrong emitted qualifier for inherited method.
    * java/net/SocketImpl.java (setOption, getOption): Ditto.
    * java/util/WeakHashMap.java (WeakEntrySet): Add non-private
    constructor to reduce amount of emitted bytecode. While this
    happens to work around a jikes 1.15 bug, it is still a useful
    patch even for correct compilers.
    * java/rmi/server/RMIClassLoader.java (MyClassLoader): Ditto.
    * gnu/java/rmi/server/UnicastRemoteCall.java
    (DummyObjectOutputStream, DummyObjectInputStream): Ditto.

2002-02-14  Eric Blake  <ebb9@email.byu.edu>

    * java/net/DatagramSocketImpl.java: Reformat (no code changes).
    * java/net/SocketImpl.java: Ditto.
    * java/rmi/server/RMIClassLoader.java: Ditto.
    * gnu/java/rmi/server/UnicastRemoteCall.java: Ditto.

2002-02-14  Mark Wielaard <mark@klomp.org>

    Thanks to Takashi Okamoto
    * java/util/Arrays.java (ArrayList.indexOf()): this.equals().
    * java/util/Arrays.java (ArrayList.lastIndexOf()): Likewise.
    * java/util/WeakHashMap.java (WeakEntry.getEntry()): this.get().
