[jira] [Commented] (SSHD-706) Error: GC overhead limit exceeded after upgrade to 1.3.0

["Goldstein Lyor (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SSHD-706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15589259#comment-15589259 ] 

Goldstein Lyor commented on SSHD-706:
-------------------------------------

A few remarks:

- Version 1.3 was released with MINA 2.0.14 as its declared dependency - version 2.0.15 is still relatively new and thus perhaps not thoroughly tested. Please re-run the checks with the 2.0.14 version.
- I have upgraded version 1.4.0 (snapshot) to MINA 2.0.15 and have run the SSHD unit tests countless times (mostly on Windows but also quite a few times on Unbuntu and Fedora) without any problem. Please clone the latest version and re-run the tests
- Reminder - as of version 1.3, Java 8+ is the minimum required - please make sure you have an up-to-date version of it
- Specifically, [GC overhead limit exceeded|http://stackoverflow.com/questions/1393486/error-java-lang-outofmemoryerror-gc-overhead-limit-exceeded] indicates some kind of external memory constraint imposed on the JVM. While not explicitly so, it may be the case that 1.3 + Java 8 combinationrequire slightly more memory. I recommend reviewing any "tweaks" and non-standard switches used to run the test code.
