How to detect cause of this crash from Crashlytics? - java

Suddenly my app started to crash enormously. I checked Crashlytics report but it doesn't tell me much. This is what it says, hopefully someone could give me a hint if had same/similar problem..

This seems to be related to a known jmDNS bug that was supposedly fixed a long time ago1:
https://sourceforge.net/p/jmdns/bugs/101/
https://sourceforge.net/p/jmdns/mailman/jmdns-discuss/thread/4EA5B242.4070003#gmail.com/
Apparently, the problem is triggered by lookup of malformed DNS names: see last email in discussion thread.
I suggest that you add some diagnostics to your app to find out what name your code is attempting to lookup.
1 - I have my doubts that it was actually fixed ... based on the discussion thread.

Codename One - Can`t make simple build

Ive try to send basic Android Build as tutorial says but Im getting this error. PS: I never would made any build before, and every day this message persists. (I`m using the Free account).
build-for-android-device:
[codeNameOne] You have a build in progress within the queue. Only one build may be active at a time
Someone may help me?
Looking at our support logs I think this was an issue that was resolved by a support engineer. The issue was related to an email account containing a + sign in the address specifically name+name#domain.com
Since our system uses emails to identify users this caused some issues and failed to show builds that went thru. So there was a build stuck in queue that never got built...
Restart your IDE, operation system.
You have queue of build right now.

Why use the value "mIsBootImageOnDisk " in service DeviceStorageMonitorService

I see the git log and find the change If53c236058a7237d735c2344a715cf0a36301f9b, it added a final value mIsBootImageOnDisk in the constructor function DeviceStorageMonitorService. But, it seems useless! Who can tell me?
I see the modification is for Bug: 17679443. Who can tell me where to see the bug information ?
enter image description here
There seems to be no entry for 17679443 in the Android Open Source Project - Issue Tracker. I'm going to guess that this is an internal bug number. The error comes from what the documentation describes as retrieving the boot class path from disk storage rather than the dirty pages in memory (the method itself calls isBootClassPathOnDisk which has a native implementation in the art runtime dalvik_system_VMRuntime.cc). I'm experiencing this error now as it processed the arm instruction set (the only instruction set processed by the system). I'm wondering if I'm experiencing a permission issue of some sort that does not allow the image header to be read properly.
The error message that results from not having enough storage space is completing misleading as I'm looking at a df listing where my system partition has 730 MB free and the data partition has 4.8 GB free (actually all the mounted partitions > 250 MB).
Hopefully, someone else will have a solution to this issue. I would hate to have to resort to stubbing out the method with a return true just to get rid of the notification -- there is probably an issue elsewhere in my firmware that needs to be fixed.
So my answer to this question, which I don't need clarification from the OP on to answer, is that there is nothing you can do right now. There are no obvious user forums either here on StackOverflow, in the AOSP issue tracker, or on another user forum like NXP/Freescale (for example) where a better answer or even background to this bug is provided.

GWT- SDK upgrade issue

I recently came across a bug with an unresolved issue in SDK 2.2 and, as its fixed in 2.5, decided to explore a switch.
Now I am new to GWT and I have no idea of the effects of doing such a switch, but figured it couldn't hurt to mess around locally. I went ahead and successfully updated to 2.5 locally to test and can run with no errors. However many of the text boxes have changed appearance and my navigation bar disappeared, etc...
Is this type of behavior normal after an update? If so I cant imagine why anyone would be in a hurry to do so, as spending enormous amounts of time to modify all pages is pretty unrealistic. Is there maybe some type of quick fix or an error i may have made to cause this?
If you want to put a lot of resources into a GWT project it is always a good idea to check regularly how the project is going on. On the release-note page you can check what's new and what has been deprecated. This way you can make an informed and rational decision whenever you want to update. This is very important since going from an old version (say 1.0) to a new one (i.e 2.5.1) might give some headaches to the programmers. Spendind half-an-hour checking what's going on every month will make your life easier.
GWT has an issue tracker where you can see the open issues and what has been resolved. Many issues have never been fixed, but I read the GWT team intend to solve the 100 most important issues for the next release. GWT is now open-source and you can contribute to its development whenever you know of to fix one of those issues.
Last but not least: many people say a lot of things, which are not always correct (including on Stack Overflow). Always dubble check before making important decisions.
Giving this advice is all I can do for you so far...
Yet, if you give me some info about that bug you expected to be fixed and the exact name of that "navigation bar" widget you might find out information on the sites above to check their status. But I can't search that for you if I don't know what the bug was and the name of the widget that is broken. Also, when you say "many of the textboxes" I understand it's not every textbox that's broken but some variant your are using in some particular places. More information would also be needed...

Java/SWT: an error has occurred see log for more

We are seeing this very generic error pop up in some circumstances, but we can't seem to track down what is generating it and I'm hoping someone has some insight into where to begin. We have multiple client machines all running the same version of our software, build with SWT, and all hitting the same server, but not everyone gets this error. Nothing is showing up in our client or server logs and I have no idea what log file this error may be referring to, so it's not an error that we are catching anywhere and we have no details about this. Since it's a pop-up message that leads me to think it may be an SWT error. I've seen people mention this error when using Eclipse, but I haven't found where anyone mentioned it in an application they built.
I know this is vague, but I don't have much more to go on. Does anyone have an idea where to start looking for culprits?
Thanks
You're building an RCP application? In that case, this error is talking about the Eclipse platform log.
There should be a .metadata\.log file in your program's instance location. If you do not know your instance location, you can query it by calling:
Platform.getInstanceLocation();

No row with the given argument - Hibernate, Java

I am using hibernate in my java dynamic project and since last week I am getting one exception called "No row with the given identifier exist[#entity(0)]. I found same problem asked earlier and I did same as suggested but problem persisted. I tried using "not-found=ignore" case as well but it doesn't work. Even the project is working fine # Production but here # development is quite disturbing. Please help me.
Maybe this can help explain it.
Just a suggestion: whenever I get an error message of any kind, I immediately cut & paste it into a Google search to see what comes back. It's highly unlikely that I'm the first person to encounter a problem.
