ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 6.1.7601]

A DESCRIPTION OF THE PROBLEM :
Two instances of the same MimeType fails on equals().
Match will work, but it seems like missing and equals implementation.

@Test
public void testMimeTypeEquals() {
try {
MimeType mt1 = new MimeType("application/xml");
MimeType mt2 = new MimeType("application/xml");
assertTrue(mt1.equals(mt2));
assertTrue(mt2.equals(mt1));
assertTrue(mt1.equals(mt1));
assertTrue(mt2.equals(mt2));
} catch (MimeTypeParseException e) {
fail(e.getMessage());
}
}

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run test

@Test
public void testMimeTypeEquals() {
try {
MimeType mt1 = new MimeType("application/xml");
MimeType mt2 = new MimeType("application/xml");
assertTrue(mt1.equals(mt2));
assertTrue(mt2.equals(mt1));
assertTrue(mt1.equals(mt1));
assertTrue(mt2.equals(mt2));
} catch (MimeTypeParseException e) {
fail(e.getMessage());
}
}

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
True on all 4 accounts.
ACTUAL -
False on all 4 accounts

REPRODUCIBILITY :
This bug can be reproduced always.
