I did a Quick try with "https://www.eclipse.org/tycho/sitedocs/tycho-surefire/tycho-surefire-plugin/test-mojo.html#useJDK <https://www.eclipse.org/tycho/sitedocs/tycho-surefire/tycho-surefire-plugin/test-mojo.html#useJDK>” 
1. Had a local ~/.m2/toolchains.xml 
2. Updated “Application/uitest/pom.xml” with  <useJDK>JavaSE-11</useJDK> 

3. Tried Mocking with “JavaSE-10” even though I had pointed the “jdkHome” to JDK 11 , and it failed with 
[ERROR] Failed to execute goal org.eclipse.tycho:tycho-surefire-plugin:1.2.0:test (default-test) on project org.openjdk.jmc.browser.uitest: Unable to parse configuration of mojo org.eclipse.tycho:tycho-surefire-plugin:1.2.0:test: Cannot convert 'JavaSE-10' to Enum: No enum constant org.eclipse.tycho.core.maven.ToolchainProvider.JDKUsage.JavaSE-10 -> [Help 1]

Let’s not explore much with ‘useJDK’ until tycho plugin is fully capable with JDK 11.

With this "JavaSE-11” wasn’t recognised by tycho ! (https://bugs.eclipse.org/bugs/show_bug.cgi?id=532302 <https://bugs.eclipse.org/bugs/show_bug.cgi?id=532302> , https://stackoverflow.com/questions/52607910/eclipse-tycho-java-11-unknown-osgi-execution-environment-javase-11 <https://stackoverflow.com/questions/52607910/eclipse-tycho-java-11-unknown-osgi-execution-environment-javase-11>) 
	"Caused by: org.eclipse.tycho.core.ee.UnknownEnvironmentException: Unknown OSGi execution environment: 'JavaSE-11’”
Have to wait until Eclipse 4.10 and with tycho 1.3.0+ 

I will raise a JBS with this details (tycho not recognising JavaSE-11) and will target the fix when we use Eclipse 4.10 and above. 

Until then Please use JMC-6194 for further review and commit.
