JR57182: LOGGING NUMEROUS ASSETS IS SLOW WHEN YOU USE THE TOSTRING() METHOD OF THE MANAGEDASSETCLASSLOADER

Downloading IBM Business Process Manager V8.5.7 Cumulative Fix 2017.03

APAR status

• Closed as program error.

Error description

• The public method toString() of the ManagedAssetClassLoader
  prints the internal details of its classloader and the details
  of all its managed assets.
  
  For example, the ScopeManager class prints information about any
  unknown or unexpected classloader it encounters at run time,
  resulting in log statements like
  
      [12/7/16 11:17:14:571 GMT-05:00] 0000015d ScopeManager
  CWLAG0209I: A foreign classloader  * * *
  com.lombardisoftware.server.core.ManagedAssetClassLoader * * *
  
  As a result, performance slows down when numerous assets are
  being logged.
  

Local fix

Problem summary

• Any code that uses an instance of ManagedAssetClassloader in its
  logging invokes the public toString() method, potentially
  causing the time-consuming logging algorithm to run although the
  detailed information is not required.

Problem conclusion

• A fix is available for IBM BPM V8.5.7 cumulative fix 2017.03
  that changes the the public toString() method so that only the
  key data, such as the class name and the current and the initial
  size of the static ManagedAssetClassLoader cache, is printed.
  With this fix installed, additional details are logged by the
  specific class trace only.
  
  Furthermore, the ManagedAssetClassLoader class has been removed
  from the component logger WLE.wle=all. You can trace the
  ManagedAssetClassLoader class by using the trace specification
  
  "com.lombardisoftware.server.core.*=finer" -> logs the entry and
  exit trace events
  "com.lombardisoftware.server.core.*=finest" -> adds log for the
  ManagedAssetClassLoader details (formerly done by toString())
  
  To determine whether the cumulative fix is available, complete
  the following steps on Fix Central
  (http://www.ibm.com/support/fixcentral):
  
  1. On the Select product tab, select WebSphere as the product
  group, IBM Business Process Manager with your edition from the
  WebSphere options, All as the installed version, and All as the
  platform, and then click Continue.
  2. In the Text field, enter "cumulative fix", and click
  Continue.
  
  If cumulative fix 2017.03 is available, download and install it.
