Local fix

• The issue can be work around by:
   - specifying the absolute path of the executable or
   - specifying relative path based on PWD.
  

Problem summary

• ProcessBuilder does a validation to see whether the executable
  exists in the specified path. It uses the relative path based on
  current working directory while doing the validation and hence
  failed to find the executable if it exists on a relative path
  based on different directory specified using directory() method.
  

Problem conclusion

• The JDK has been updated to validate the executable from the
  relative path based on the specified directory instead of using
  current working directory.
  .
  This APAR will be fixed in the following Java Releases:
