APAR status

• Closed as program error.

Error description

• In IBM Developer for z Systems (IDz) v14.1.3, when a sequential
  dataset is part of a zOS Project that is bound to SonarQube,
  and a zOS File System Mapping entry exists that maps the dataset
  to a workstation file extension, intermittent NPE can occur when
  selecting SonarLint Issue and choosing to see it's Rule
  Description. Here is the exception that can be seen in the error
  log file:

Local fix

Problem summary

• When a sequential dataset is part of a zOS Project that is bound
   to SonarQube, and a zOS File System Mapping entry exists that
  maps the dataset to a workstation file extension, intermittent
  NPE can occur when selecting a SonarLint Issue and choosing to
  see it's Rule Description.  When the cache used to link the
  issue entry with the line of code in the file expired the
  resource could not be found causing the NullPointerException.
  

Problem conclusion

• The scenario that causes the intermittent exceptions is somewhat
   isolated.  It occurred when the cache expired for SonarLint
  issues in a sequential dataset that is part of a zOS Project,
  and matches a zOS File System Mapping entry.  A modification has
   been made to correct this issue.
