    Description

      Derby does not prevent dual boot from two different classloaders on Linux and Mac OS X.

      To reproduce run the program DualBootRepro with no derby jars in your classpath. The program assumes derby.jar is in 10.1.2.1/derby.jar, you can change the location by changing the DERBY_LIB_DIR variable.

      On Linux the output is:

      $java -cp . DualBootRepro
      Loading derby from file:10.1.2.1/derby.jar
      10.1.2.1/derby.jar
      Booted database in loader java.net.URLClassLoader@8ed465
      FAIL: Booted database in 2nd loader java.net.URLClassLoader@dc6a77

      On Windows I get the expected output.
      $ java -cp . DualBootRepro
      Loading derby from file:10.1.2.1/derby.jar
      10.1.2.1/derby.jar
      Booted database in loader java.net.URLClassLoader@1ac04e8
      PASS: Expected exception for dualboot:Another instance of Derby may have already booted the database D:\marsden\repro\dualboot\mydb.
