Subject [jira] [Commented] (GROOVY-8865) Specifying initial heap size results in an error
Date Thu, 01 Nov 2018 20:57:00 GMT

    [ https://issues.apache.org/jira/browse/GROOVY-8865?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16672184#comment-16672184

Paul King commented on GROOVY-8865:
-----------------------------------

Okay, understood. Looks like we hard code a value for -Xmx:

https://github.com/apache/groovy/blob/master/src/bin/startGroovy.bat#L262

Obviously we should not do that if a user supplies their own -Xmx and/or the value should
be at least as big as any -Xms setting.

>             Project: Groovy
>          Issue Type: Bug
>          Components: groovy-runtime
>    Affects Versions: 2.5.3
>         Environment: Windows 10, OpenJDK 11.0.1
>            Reporter: Rostyslav Smirnov
>            Priority: Major

> On Windows, setting initial heap size greater than 128MB without setting maximum heap
size, e.g. JAVA_OPTS=-Xms1G, results in the following error:
> {quote}Error occurred during initialization of VM
> Initial heap size set to a larger value than the maximum heap size
> {quote}
> This works fine on Linux. And it is a valid JVM parameter, since JVM will set its maximum
heap to be the greater of its default value and initial heap size.
