Wrong Java gets picked up when building an example for Android

Steps to reproduce:

1. Install Qt 5.13.0-beta4 (with QtC 4.9.1 and QtC 4.10.0-beta1) from staging servers
2. Select e.g. 'wiggly' example from Welcome Screen
3. Launch QtC 4.10.0-beta1 and set the Java JDK, Android SDK and NDK paths in Devices
4. Run 'qmake'
5. Build

Expected result:

The example gets built

Actual result:

Build fails with:

> Could not find tools.jar. Please check that C:\Program Files\Java\jre1.8.0_171 contains a valid JDK installation. 

A wrong Java path is picked (In C:\Program Files\Java\ I have 'jre1.8.0_171'  and 'jdk1.8.0_121'). The AndroidConfigurations is:

[AndroidConfigurations]
ChangeTimeStamp=1534154168
SDKLocation=C:/utils/Android
SDKManagerToolArgs=@Invalid()
NDKLocation=C:/utils/Android/android-ndk-r19c
OpenJDKLocation=C:/Program Files/Java/jdk1.8.0_121
KeystoreLocation=
PartitionSize=1024
AutomatiKitCreation=true
ToolchainHost=windows
DeviceQmlsceneCommand=org.qtproject.example.qmlscene/org.qtproject.qt5.android.bindings.QtActivity
MakeExtraSearchDirectory=C:/Users/QT/RTA/qt5/Tools/mingw530_32/bin
AntLocation=C:/Program Files/apache-ant/apache-ant-1.10.1/bin/ant.bat
UseGradle=false 

But the wrong Java seems to be picked up at build time. If I removed the jre from the location, the example still didn't seem to get built completely. Using the same Qt version (and the same Android settings), but QtC 4.9.1, this did not reproduce.
