Re: [Dev] ESB 4.9.0 OOM error.

 Hi All.

 I tried invoking simple REST API with ESB 4.9.0 vanilla pack on windows
 10 . I sent few request and observed the following error in the logs.

Re: [Dev] ESB 4.9.0 OOM error.

[Ajith Vitharana]

Hi Chanaka.

I found something interesting . So I had accidentally configured
 uri-template as the endpoint of my API, So after sending one request ESB
will go OOM. I can consistently reproduce this issue.
Seems this is specific to Windows.

Re: [Dev] ESB 4.9.0 OOM error.

[Chanaka Fernando]

Hi Ajith,

Thank you for reporting this issue. We haven't tested ESB 490 with Windows
10 when we were doing the release. We will investigate on this issue. Could
you please share the REST API which you have used to test this scenario?

@Shashika: Please note this and add this scenario to the testing effort of
ESB 5.0.0.
