Have you tried to add to PowerMock ignore?
'@PowerMockIgnore("javax.management.*")'
thekingn0thing
on 27 Jan 2017
Adding the annotation ^^ did not resolve the test failure.
Revised test code:
// snipped imports
@RunWith(PowerMockRunner.class)
@PrepareForTest({ AuthDBConnection.class })
@PowerMockIgnore("javax.management.*")
public class AuthDBConnectionOpenTest {
// @Ignore("Crashing, see https://github.com/powermock/powermock/issues/743")
@Test
public void testOpen() throws Exception {
createMocksAndSetExpectations();
AuthDBConnection.open();
}
private void createMocksAndSetExpectations() throws Exception {
Connection mockConnection = createMock(Connection.class);
OracleDataSource mockDS = createMock(OracleDataSource.class);
expect(mockDS.getConnection()).andReturn(mockConnection);
expect(new OracleDataSource()).andReturn(mockDS);
replay(OracleDataSource.class);
}
}

As you may see error message has changed from
java.lang.LinkageError: loader constraint violation: loader (instance of org/powermock/core/classloader/MockClassLoader) previously initiated loading for a different type with name "javax/management/MBeanServer"
to
java.lang.LinkageError: loader constraint violation in interface itable initialization: when resolving method "oracle.xdb.XMLType.getSource(Ljava/lang/Class;)Ljavax/xml/transform/Source;" the class loader (instance of org/powermock/core/classloader/MockClassLoader) of the current class, oracle/xdb/XMLType, and the class loader (instance of
) for interface java/sql/SQLXML have different Class objects for the type javax/xml/transform/Source used in the signature
Now you need add another packages to ignore. I can guess: javax.xml.* Maybe in the end the oracle.xdb.* also will be added to ignore.

This did the trick for me:
@PowerMockIgnore({
"com.sun.crypto.*",
"javax.crypto.*",
"javax.management.*",
})
