PI92278: RATIONAL DEVELOPER FOR SYSTEM Z - IDZ v14.0.0.5 INITIAL STARTUPWITH A NEW WORKSPACE TAKES LONGER DUE TO AN ERROR WITH SONARLINT

APAR status

• Closed as program error.

Error description

• Users experience errors related to SonarLint when starting IDz
  that adds several minutes of delay to the first startup.
  
  Per the stacktrace, SonarLint responds to the creation event of
  the internal IDz RemoteConfigurationFiles project by calling an
  operation that accesses RemoteConfigurationFiles, which attempts
  to create RemoteConfigurationFiles again, resulting in an error
  "The resource tree is locked for modifications".
  
  !MESSAGE Exception when creating Configuration Project
  !STACK 1
  org.eclipse.core.internal.resources.ResourceException: The
  resource tree is locked for modifications.

Local fix

• NA
  

Problem summary

• An attempt to create a new project that is already in the
  process of being created in the same thread was leading to a
  resource locked error.
  

Problem conclusion

• The second project creation attempt was a side-effect of
  attempting to compare two projects and the problem was avoided
  by comparing project names instead of the projects themselves.
  

Temporary fix
