  • Priority: Major Major
  • Resolution: Won't Fix
  • Affects Version/s: 4.0.0
  • Fix Version/s: 5.0.0
  • Component/s: Classloader
  • Security Level: Public
  • Description:
    Hide

    Because of memory leak (some object instance remain in memory and won't be garbaged), some classes cannot be unloaded. So some classloaders are not freed, and some JAR files are locked on the filesystem.
    To prevent lock, a tricky method has been added into PetalsClassLoader to unlock JAR files when the classloader is nor more needed.

    Remove this tricky method fixing memory leak, and JAR files will be unlocked.

As the risk is too big for the next release of Petals ESB (3.3.0), it will be fixed for the next one.

It was fixed as part of the switch to Java 7 (PETALSDISTRIB-109): we removed that method and used the method close provided by the JDK.
