    • Workaround: Use the file menu or the close box to exist the Sample Launcher.
  • CDV-749 Long file names are truncated when tar used on Solaris.
    • Workaround: On Solaris the gtar command should be used.
  • CDV-538 Redeployed web applications will almost certainly run into ClassCastExceptions for shared application-level objects.
  • This release supports the use of the THashMap and THashSet classes from the trove library http://trove4j.sourceforge.net. Version 1.1b5 is officially supported in this release. THashMap and THashSet support the use of user-customized hashing strategies through the TObjectHashingStrategy interface. When distributing THashMap/THashSet instances, only the default hashing strategy is supported. Any custom hash strategy will not be honored across the cluster.
  • OOME in Permspace 
    SEVERE: Error deploying web application directory search
org.apache.commons.logging.LogConfigurationException:
java.lang.OutOfMemoryError: PermGen space (Caused by java.lang.OutOfMemoryError: PermGen space) at
org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.java:538) at ...

    Increase the permspace by passing the correct jvm arguments.

  • Changes to the default batch size made to improve memory performance may in some cases affect a class of performance tests. Please contact support@terracottatech.com if this occurs.

Forge Known Issues

  • FORGE-260 Cannot fault CGLIB instances.
    • Workaround: tim-cglib should only be used with hibernate.
  • FORGE-270 Setting timeToIdleSeconds wth timeToLiveSeconds in ehcache.xml causes excess TPS.
    • Workaround: Do not use these settings in conjunction with one another.
  • FORGE-214 Maven-surefire-plugin issue on windows. Issue filed against the surefire plugin SUREFIRE-461.
    • Workaround: The workaround is to instruct Maven to skip the test phase of the build when installing the TIM. This is done by passing the following on the command-line: -Dmaven.test.skip=true
