Blocker Description
I've been developing an R interface to the Tika batch processor for the past month ( see: https://github.com/predict-r/rtika ), and this software is awesome. I use the command line to call the batch processor, and my code has worked on Ubuntu, Windows 10 and OS X. Several people have been testing my code as well. Its been working.
A few days ago I found an issue with the batch processor on OS X.
When calling the batch processor with the tika-app-1.17.jar on a path with spaces in it, Tika starts to continually restart.
Here is an example of calling the jar when the path has spaces. It produces this error, and the unexpected restarts:
java -Djava.awt.headless=true -jar '/Users/sasha/Downloads/space folder/tika-app.jar' -maxRestarts 1 -t -i '/' -o '/var/folders/nr/74rgb64s3n98yccxwbv6vsxw0000gn/T/Rtmp9VEJvX/rtika_dircf81200b313e' -fileList '/var/folders/nr/74rgb64s3n98yccxwbv6vsxw0000gn/T/Rtmp9VEJvX/rtika_filecf81530d27ee' INFO about to start driver INFO BatchProcess: Error: Could not find or load main class org.apache.tika.batch.fs.FSBatchProcessCLI INFO BatchProcess: Caused by: java.lang.ClassNotFoundException: org.apache.tika.batch.fs.FSBatchProcessCLI INFO The child process has finished with an exit value of: 1 WARN Restarting on unexpected restart code: 1 WARN Must restart process (exitValue=1 numRestarts=0 receivedRestartMessage=false) INFO BatchProcess: Error: Could not find or load main class org.apache.tika.batch.fs.FSBatchProcessCLI INFO BatchProcess: Caused by: java.lang.ClassNotFoundException: org.apache.tika.batch.fs.FSBatchProcessCLI INFO The child process has finished with an exit value of: 1 WARN Restarting on unexpected restart code: 1 WARN Hit the maximum number of process restarts. Driver is shutting down now. INFO Process driver has completed
The error ALSO occurs with double quotes also around the jar.
Now, in contrast, calling the jar when the path does not have spaces produces absolutely NO error:
java -Djava.awt.headless=true -jar '/Users/sasha/Downloads/tika-app.jar' -maxRestarts 1 -t -i '/' -o '/var/folders/nr/74rgb64s3n98yccxwbv6vsxw0000gn/T/Rtmp9VEJvX/rtika_dircf81200b313e' -fileList '/var/folders/nr/74rgb64s3n98yccxwbv6vsxw0000gn/T/Rtmp9VEJvX/rtika_filecf81530d27ee' INFO about to start driver INFO BatchProcess: log4j:WARN No appenders could be found for logger (org.apache.tika.batch.fs.FSBatchProcessCLI).

Further, and what makes this a batch processor issue, is that that path with the space in it produces absolutely NO error in the normal Tika CLI mode either:
java -jar '/Users/sasha/Downloads/space folder/tika-app.jar' -t /Library/Frameworks/R.framework/Versions/3.4/Resources/library/rtika/extdata/jsonlite.pdf
The last two examples work, but the first does not.
The only difference is the first is calling the batch processor, and that is causing restarts with whatever file.
