Internal Debugger Exception

System.NullReferenceException: Object reference not set to an instance of an object.
at net.sf.jni4net.jni.JNIEnv.CallStaticObjectMethodPtr(Class clazz, MethodId methodIdNative, Value[] args)
at flash.tools.debugger.Bootstrap.sessionManager()
at FlashDebugger.FlashInterface.Start()
at FlashDebugger.DebuggerManager.bgWorker_DoWork(Object sender, DoWorkEventArgs e)

At first run the application works and debugs fine, at subsequent runs it's shows this error message.

I'm running FlashDevelop 5.3.1.67 Development version.

Originally thought it was related to this: #1855, but upon further investigation seems to be a separate issue.

Java Location:
echo %JAVA_HOME%
C:\Program Files (x86)\Java\jre6

Same with Development version 5.3.1.67

Maybe this is fixed or improved in https://ci.appveyor.com/api/buildjobs/pb46pxtxd6362jce/artifacts/FlashDevelop%2FInstaller%2FBinary%2FFlashDevelopPR_1956.zip

Same with 5.3.1.27

Yeah I'm still getting the same issues even after a clean install not sure what's going on with it cannot connect to the debugger.

When reverting back to 5.0.2 working fine with the same setup and environment variables.
