Re: [Dev] [ESB] EmptyStackException when resuming a paused message processor

Hi All, Did this fix included to last release? I'm getting exact same issue in API Manager 1.10 with high concurrency. Getting exact same NPE mentioned in below JIRA[1] [1]https://wso2.org/jira/browse/ESBJAVA-4142 Thanks, sanjeewa. On Wed, Oct 14, 2015 at 11:09 AM, Jagath Sisirakumara

Re: [Dev] [ESB] EmptyStackException when resuming a paused message processor

Hi ESB folks, Can we get a milestone release of synapse and carbon-mediation including this fix and another PR I sent to synapse? We have to do a milestone release of API Manager this week. Thanks, NuwanD. On Mon, Oct 12, 2015 at 11:43 AM, Nuwan Dias wrote: > Thanks a lot

Re: [Dev] [ESB] EmptyStackException when resuming a paused message processor

Hi Nuwan, Our plan is to do the first milestone release end of next week. With this we hope to incorporate latest carbon-deployment and kernel releases (if it released during this week). Thanks. On Wed, Oct 14, 2015 at 11:07 AM, Chanaka Fernando wrote: > [Adding Jagath] > >

Re: [Dev] [ESB] EmptyStackException when resuming a paused message processor

Hi Sameera, Your judgment is correct and it helped us to find the root cause :). I'll fix the code from carbon-mediation side. Thanks for your input. On Fri, Oct 9, 2015 at 3:19 PM, Sameera Jayasoma wrote: > Hi Chanaka, > > You don't need to destroy the current context. This

Re: [Dev] [ESB] EmptyStackException when resuming a paused message processor

Hi Chanaka, You don't need to destroy the current context. This part is handle by the Kernel code. Users of the CarbonContext API do not need to worry about destroying the context. Who has done this change? So my initial judgment is correct. :) Stack cannot become empty. Thanks, Sameera. On

Re: [Dev] [ESB] EmptyStackException when resuming a paused message processor

Hi all, Will this be fixed in kernel 4.4.2? Its causing integration test failures in API Manager and we would like this to be fixed soon. Thanks, NuwanD. On Thu, Oct 8, 2015 at 6:22 PM, Chanaka Fernando wrote: > [Adding Kishanthan] > > On Thu, Oct 8, 2015 at 6:14 PM,

Re: [Dev] [ESB] EmptyStackException when resuming a paused message processor

Hi NuwanD, The fix is not in kernel but in carbon-mediation. What I need is kernel team's opinion on usage of the aforementioned method. If we can get their input, fix is straightforward. On Thu, Oct 8, 2015 at 9:58 PM, Nuwan Dias wrote: > Hi all, > > Will this be fixed in

Re: [Dev] [ESB] EmptyStackException when resuming a paused message processor

Hi Sameera/KasunG, I have debugged the code to find the root cause for this empty stack exception. This is causing several other issues at the ESB layer. What actually happens is that inside the MultitenantMessageReceiver.processRequest() method, we have the following code segment. try {

I understand, but we need to understand why that stack becomes empty. AFAIK, if we follow the proper APIs, stack should not become empty On Tue, Jul 7, 2015 at 5:47 PM, Kasun Indrasiri ka...@wso2.com wrote: Yeah, we should always check for an empty stack. On Tue, Jul 7, 2015 at 5:17 PM,

Hi Jagath, Can you debug and see whey the stack becomes empty? Thats a serious problem. Stack should be become empty here. Checking whether the stack is empty will stop the error log, but it doesn't fix the actual problem here. On Wed, Jul 8, 2015 at 10:50 AM, Sameera Jayasoma same...@wso2.com
