Develop builds for me. And travis seems happy - https://travis-ci.org/apache/incubator-geode
But this is actually pretty weird. In Intellij at least, it thinks that lambda maps to a SerializableCallable even though it doesn't return a value. I think maybe that's due to the while(true) part. If I comment that out, it maps to a runnable. It seems like this particular lambda actually *is* ambiguous since it will never return normally, it could be either a callable or a runnable. What JDK and what revision are you building with? Maybe some newer JDK is complaining about this? -Dan -Dan On Thu, Jun 2, 2016 at 1:58 PM, Anilkumar Gingade <aging...@pivotal.io> wrote: > Hi Devs, > > Anyone seeing this issue: > > > :geode-core:compileTestJava/export/india1/users/agingade/src/gemfire/open/geode-core/src/test/java/com/gemstone/gemfire/management/internal/security/MultiUserDUnitTest.java:62: > error: reference to invokeAsync is ambiguous > > AsyncInvocation vm1Invoke = vm1.invokeAsync("run as data-reader", () -> > { > > ^ > > both method invokeAsync(String,SerializableRunnableIF) in VM and method > <T>invokeAsync(String,SerializableCallableIF<T>) in VM match > > where T is a type-variable: > > T extends Object declared in method > <T>invokeAsync(String,SerializableCallableIF<T>) > > > /export/india1/users/agingade/src/gemfire/open/geode-core/src/test/java/com/gemstone/gemfire/security/templates/LdapUserAuthenticator.java:89: > warning: LdapCtxFactory is internal proprietary API and may be removed in a > future release > > env.put(Context.INITIAL_CONTEXT_FACTORY, > com.sun.jndi.ldap.LdapCtxFactory.class.getName()); > > ^ > > Note: Some input files use or override a deprecated API. > > Note: Recompile with -Xlint:deprecation for details. > > Note: Some input files use unchecked or unsafe operations. > > Note: Recompile with -Xlint:unchecked for details. > > 1 error > > > -Anil. >
