Re: Wicket 7 - OutOfMemory PermGen

[Martin Grigorov]

Hi,

Do you use 7.0.0?
Because there was a problem -
https://issues.apache.org/jira/browse/WICKET-5978
It is fixed in 7.1.0

Re: Wicket 7 - OutOfMemory PermGen

[Mihir Chhaya]

First, Thanks Francois for your quick looking into this.

The SearchDealerPage is created as below. The link is menu option.

BookmarkablePageLink dealerInquiryLink = new
BookmarkablePageLink("dealerInquiryLink", SearchDealerPage.class,
searchPageParameters);


Thanks,

-Mihir.

Sorry, it's seems that there is a problem when you instanciate the

How you instanciate it ?

Re: Wicket 7 - OutOfMemory PermGen

[Christos Stieglitz]

Just in case:
i recently had exactly the same problem. It turned out that it is not
related to Wicket at all.

Do you use a Java8 JDK? Do you compile for Java7?

The PermGen Exception happens at random times [*], always at the same
line in the code. Hence you assume you have some faulty code there.
But it is a JDK 8 -> 7 compatibility mode issue, not Wicket. 
Before losing lots of hours (like i did) just check the settings of your
IDE.

[*] under Windows 64bit twice as often as under Linux.

Wicket 7 - OutOfMemory PermGen

[Mihir Chhaya]

Hello,

I am using Wicket 7 + Spring 4.x + Hibernate 4.x (recently migrated from
Wicket 1.4).

Since deployment of the app on JBOSS, the application is crashing with
OutOfMemory error for PermGen. We are at the point of rolling back to 1.4
as application was working fine without such issue; doesn't necessarily
mean Wicket 7 is an issue. There is OutOfMemory error reported with
Wicket+Spring for Wicket 6.20, but the issue status shows fixed.

JBOSS application server PermGen is 512MB, so doesn't seem that be an issue.

Here is the stacktrace (First and Second). Second seems to be the result of
First one.

Could anybody shade some light? I ran with some load on my local (tomcat as
well as on JBOSS) and monitored using VisualVM. PermGen is remaining
between 20 and 100 MB.
