[jira] Commented: (DERBY-700) Derby does not prevent dual boot of
database from different classloaders on Linux and Mac OS X
[ https://issues.apache.org/jira/browse/DERBY-700?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12750601#action_12750601 ]
Mamta A. Satoor commented on DERBY-700:
---------------------------------------
Rick, I was wondering if you knew the correlation between DERBY-700 and DERBY-4361. testDefault fixture in ErrorStreamTest has been failing consistently after the checkin went in for DERBY-700. If the test orders are changed and ErrorStreamTest is run after the test ClassLoaderBootTest which was added for DERBY-700, testDefault fixture does not fail anymore. I will look further into what the relationship between the 2 jira entries might be but I thought I would check if it rings a bell for you. Thanks

> 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.
