Subject [jira] Commented: (LUCENE-2834) don't spawn thread statically in FSDirectory on Mac OS X
Date Mon, 27 Dec 2010 12:51:46 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-2834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12975245#action_12975245

Uwe Schindler commented on LUCENE-2834:
---------------------------------------

This thread is a "system thread" and has nothing to do with Lucene. Killing it is something
you should not do in a running JVM. To remove it from the exclusion list, just get a MessageDigest
or somehow else access the PKCS library before you build the system thread map (the static
while loop in LTC).

Sorry, this time I don't agree with you and will revert all commits like that!

> on the Mac, creating the digester starts up a PKCS11 thread.
> I do not think threads should be created statically (I have this same issue with TimeLimitedCollector
and also FilterManager).
> Uwe discussed removing this md5 digester, I don't care if we remove it or not, just as
long as it doesn't create a thread,
> and just as long as it doesn't use the system default locale.
