We are using redisson-3.11.3 in tomcat webapp which has dependency to lz4-java (version 1.4.0) as following: https://github.com/redisson/redisson/blob/redisson-3.11.3/redisson/src/main/java/org/redisson/codec/LZ4Codec.java
The tomcat\bin\service.bat has -Djava.io.tmpdir=\tomcat\temp which seems to be getting cleared when the tomcat is restarted.
We observe that lots of (21k+ files occupying 3.2+ GB) liblz4-java*.so files are getting generated in c:\windows\temp (and in c:\Users<userName>\AppData\Local\Temp in another machine)
- Is this due to lz4-java version 1.4.0 and due to the code mentioned above?
- Will this be cleaned up if lz4-java version 1.7.1 is used? The commit seems to be clearing files from java.io.tmpdir but in our machine the files are generated in directories other than java.io.tmpdir.
- How to identify which code is generating these files?
- How to reproduce the issue? Merely using the library does NOT seem to leave the residual files.
- What is the ideal way to fix this?
Note:
Asked the question to github community but haven't got any response yet: https://github.com/lz4/lz4-java/issues/165 .
