Stian Soiland-Reyes commented on TAVERNA-920:
---------------------------------------------
I'm afraid we are dealing with a Heisenbug.. while the pom.xml "fix" I added
seemed to work around it when I tested it, in the
taverna-language-0.15.1-incubating-RC3 the bug reappears - but it seems
randomly. So if I build with {{mvn clean verify}} it seems to happen alot,
while if I build with {{mvn clean install}} it only happens now and then.
(Also it seems the maven-bundle-plugin causes the build to restart multiple
times on {{mvn install}} - is this related to how this bug would not occur?)
Basically it's a real bug the test detect, because when it fails, then
META-INF/container.xml of wfbundle says:
{code:xml}
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns3:container xmlns="http://www.w3.org/2001/04/xmlenc#";
xmlns:ns2="http://www.w3.org/2000/09/xmldsig#";
xmlns:ns3="urn:oasis:names:tc:opendocument:xmlns:container"/>
{code}
while the ODF Container spec sadly mandates fixed namespaces:
{code:xml}
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<container xmlns:xmlenc="http://www.w3.org/2001/04/xmlenc#";
xmlns:xmldsig="http://www.w3.org/2000/09/xmldsig#";
xmlns="urn:oasis:names:tc:opendocument:xmlns:container"/>
{code}
Perhaps there's an SPI inside Java that randomly picks between two different
xerces-implementations - as JDK has a built-in copy of jaxb and xerces, but
moved to an internal {{com.sun}} package.
