Subject [jira] Resolved: (HARMONY-665) [classlib][nio]Charset.encode()/decode() should be more safer for multi thread using
Date Mon, 26 Jun 2006 11:41:31 GMT
     [ http://issues.apache.org/jira/browse/HARMONY-665?page=all ]
Tim Ellison resolved HARMONY-665:

    Resolution: Fixed

Thanks Paulex,

Patch applied to NIO_CHAR module at repo revision r417174.

(I still think you may be able to reduce the synchronization on the cache read/write to improve

Please check that the patch was applied as you expected.

> As discussion on the mailing list, current Harmony codes may throw exception for the
scenario below:

>               thread[i] = new Thread() {
>                   public void run() {

> String.getBytes() actually invokes Charset.encode(), while spec requires Charset.encode()
to be thread-safe. Current Harmony implementation of Charset.encode() holds lock on this Charset
instance, but doesn't synchronize on the system wide cached CharsetEncoder, so it is not safe
for multi Charset instances in multi threads to encode() concurrently.
