Error description

• You can add external assets, such as JAR files, so that you can
  use them in an IBM Business Process Manager (BPM) solution to,
  for example implement a Java integration service step. If there
  are multiple or huge  assets for a process application snapshot,
  loading the first resource (for example, a Java class) from an
  asset in a given context could take several minutes.
     The java stack of the thread loading the managed assets is
  "WebContainer : 0" J9VMThread:0x00000000090F6000,

Problem conclusion

• A fix is available for IBM BPM V8.5.0.0 that removes a

  therefore, improves the response time when loading the first
  resource.
