Description

When an exception occurs while ModulesLoader is loading a TIM into the L1, the details of the exception are discarded and only a summary message is printed to the log: “BundleActivator start failed” for instance.

This makes it very difficult to debug problems with module loading. The full details of the exception should be logged so that problems loading modules can be debugged by reading the log output.

NOTE: Be sure to test whether a call to a regular (ie. non-console) logger will have any effect here. It is possible (but I don’t know either way) that the log file has not been opened yet and thus logging to a regular logger and calling System.exit() afterwards will lose the log statement.

Need to fix this as it has (multiple times) made it difficult and time-consuming to debug monkey issues.

I think this has been fixed. Can someone give a definitive statement?

can you verify that this is fixed?

This is the same as DEV-2201, need to be fixed.

if a tim is missing, we end up printing a duplicate message followed by a stacktrace

edit samples/pojo/chatter/tc-config.xml and add a section for tim-apache-struts
start-tc-server.sh -f samples/pojo/chatter/tc-config.xml
samples/pojo/chatter/run.sh

Attempted to resolve the TIM using the following descriptors:

  groupId: org.terracotta.modules
  name   : tim-apache-struts-1.1
  version: 1.3.0-SNAPSHOT

Expected the TIM’s filename to be:

  tim-apache-struts-1.1-1.3.0-SNAPSHOT.jar

Expected these attributes to be in the manifest:

  Bundle-SymbolicName: org.terracotta.modules.tim-apache-struts-1.1
  Bundle-Version     : 1.3.0.SNAPSHOT

Searched using the following repositories:

  + /Users/nghani/__releases/mar23/terracotta-3.0.0-nightly-ee-rev12356/modules

Tried to resolve the jar file using the following paths:

  + /Users/nghani/__releases/mar23/terracotta-3.0.0-nightly-ee-rev12356/modules/org/terracotta/modules/tim-apache-struts-1.1/1.3.0-SNAPSHOT/tim-apache-struts-1.1-1.3.0-SNAPSHOT.jar
  + /Users/nghani/__releases/mar23/terracotta-3.0.0-nightly-ee-rev12356/modules/tim-apache-struts-1.1-1.3.0-SNAPSHOT.jar

If the jar file exists and is in one of the paths listed above, make sure that the Bundle-SymbolicName and Bundle-Version attribute in its manifest matches the ones that the resolver expects.

If you do not have this particular TIM or any of its dependencies installed, try using the tim-get tool’s ‘install’ command:

  $ tim-get.sh install tim-apache-struts-1.1 1.3.0-SNAPSHOT org.terracotta.modules

You can also use the tool’s ‘list’ command to see if it’s actually available:

  $ tim-get.sh list tim-apache-struts-1.1   # list anything that has 'tim-apache-struts-1.1' in it's name
  $ tim-get.sh list                         # or, list everything that is available

For more information on how to use the tim-get tool, invoke:

  $ tim-get.sh help  2009-03-27 13:33:52,388 FATAL - Exception thrown org.osgi.framework.BundleException: Unable to resolve TIM file for tim-apache-struts-1.1 version 1.3.0-SNAPSHOT (group-id: org.terracotta.modules)
