This issue doesn't stop the installation but the final installation.log has the sequence of this NULL POINTER exception.

Using VxWorks A653 v2.5.0.2 I am getting an exception being generated in tRootTask during startup:
data storage
Exception current instruction address: 0x50000120
Machine Status Register: 0x0000fb30
Data Exception Address Register: 0x00000008
Integer Exception Register XER: 0x00000000
Condition Register: 0x40000088
Exception Syndrome Register: 0x01000000
Partition Domain ID: 0x007539a0
Task: 0x521f5920 "tRootTask"
the tRootTask does spawn a number of other kernel tasks and also creates a task for the user partition. But the entry point to the user task in the user partition never seems to run (printf() statement is not hit). After the exception occurs it is possible to attach a debugger, but the tRootTask itself is deleted by the exception. If I access the shell after the exception, attempting to display the contents at 0x50000000 contains fails, as if it is unmapped memory. This may be the root cause of the exception, but why it's inaccessible is unclear.
So I am searching for a way to debug why the exception is happening. I'm new to this OS.itself
Look in your linker map for the
"Exception current instruction address: 0x50000120"
Or if the shell has "lkup"
-> lkup 0x50000120
should give the nearest global function that's throwing exception.
Data Exception Address Register: 0x00000008
looks like zero page access, but you need decipher the "Exception Syndrome Register" in PowerPC manual to see if it's the right condition code?
"tRootTask" is the first thread in the context, so it's some sort of startup code that's failing. But it's so early, you probably need a JTAG debugger to get a breakpoint on it.
When I create a new project (web api) in Visual Studio 2019, I try running the project but I got the following error:
An unhandled exception occurred while processing the request.
SqlException: Invalid object name 'Books'.
Microsoft.Data.SqlClient.SqlCommand+<>c.b__169_0(Task result)
Did you check spelling in SqlDataReader? For me, I was misspelled. If the spelling is correct, any chance are you re-using the same name of an existing environmental variable for a different database on the same SQL Server? If the answer is yes it can be issue too.
Caught exception during comparison] Exception[org.xmlunit.XMLUnitException] follows: org.xmlunit.XMLUnitException: Caught exception during comparison at org.xmlunit.diff.DOMDifferenceEngine.compare(DOMDifferenceEngine.java:88) at org.xmlunit.builder.DiffBuilder.build(DiffBuilder.java:386)
Am getting the above error when i make continuous call for

I started learning groovy yesterday and have been enjoying it thus far until I got to the part of the book where I have to take in inputs from the user using console().readLine() but I keep getting this error
Caught: java.lang.NullPointerException: Cannot invoke method readLine() on null object java.lang.NullPointerException: Cannot invoke method readLine() on null object
at com.usl.NewCodes.run(NewCodes.groovy:30)
I have tried it in intelliJ both as a groovy script and in a class. I even went on to try it in the groovyConsole yet it still throws an error.
Here is the code
print("What is your name ");
def fName = System.console().readLine()
println("Hello" + fName)
Thanks
If you are using any IDE for Groovy, the input / output console will not be available to you hence throwing null pointer exception so, you can use the following, If you are using Intellij enable groovy console from Tools -> groovy console for I/O.
println "What is your name?"
println "Your name is:"+System.in.newReader().readLine()
I have the following code which used to work and now no longer works:
collectionUri = New Uri(txtServerName.Text)
Dim tpc As New TfsTeamProjectCollection(collectionUri)
workItemStore = tpc.GetService(Of WorkItemStore)()
teamProject = workItemStore.Projects(txtProjectName.Text)
When my application hits the line: workItemStore = tpc.GetService(Of WorkItemStore)() I get the following error:
ArgumentException occurred
A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll
Additional information:
Requested value 'Information' was not found.
{System.ArgumentException: Requested value 'Information' was not found. at System.Enum.EnumResult.SetFailure(ParseFailureKind failure, String failureMessageID, Object failureMessageFormatArgument)}
I have uninstalled and re-installed Visual Studio 2013 ... same results. I have tried the application on another computer and it works just fine so I know my code is good.
I haven't touched this app in a few months so I'm not certain what would have changed. Any ideas?
Thanks.
