the tomcat server in production crashes while javathread "finalizer" runs in jvm hs_err_pid below.

also, error comes java native code malloc_consolidate inside libc.so.

-dsun.zip.disablememorymapping=true should fix issue, zip implementation improved in jdk 9, crash suggest that, during finalizer tries close file handle, still not released. upgrading jdk9 should avoid issue - https://jdk9.java.net/download/
