Subject [jira] [Commented] (IGNITE-255) Jvm8 warns that MaxPermSize is ignored
Date Mon, 11 Jan 2016 10:36:39 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15091750#comment-15091750

Denis Magda commented on IGNITE-255:
------------------------------------

Saikat,

I'm quite sure that the proposed solution won't work for the versions that contain dashes
or underscore (like, 1.3.1-beta or 1.3.1_05). However such versions strings are possible according
to [1]

Probably we can leverage regexp there somehow. What do you think? The regexp can just take
a major version.

Also we must be sure that the scripts will work not only on Oracle JDK but on others as well:
at least on OpenJdk, IBM JDK.

If it won't be possible to calc the version properly for all the cases I would omit setting
MaxPermSize/MaxMetaspaceSize at all.

> Jaba8 doesn't support MaxPermSize anymore. Either we should replace it in ignite.sh by
a similar option of Java8 or set it only if ignite.sh started for Java7
