[arquillian-issues] [JBoss JIRA] (ARQGRA-245) Returning a value from Function<T, V> in WebDriverwait cannot be compiled with JDK7

Returning a value from Function<T,V> in WebDriverwait cannot be compiled with JDK7 ---------------------------------------------------------------------------------- Key: ARQGRA-245 URL: https://issues.jboss.org/browse/ARQGRA-245 Project: Arquillian Graphene Issue Type: Bug Components: core Affects Versions: 2.0.0.Alpha2 Reporter: Karel Piwko Assignee: Jan Papousek Fix For: 2.0.0.Alpha3 Attachments: WebElementUntilFunction.java When compiling with JDK7, following error happens: {code} @FindBy(className = "failed") WebElement failedCasesCount; @FindBy(className = "passed") WebElement passedCasesCount; @FindBy(className = "total") WebElement totalCasesCount; @FindBy(id = "qunit-tests") QUnitResultsFragment results; private URL pageUrl; private long timeout = 60; private TimeUnit unit = TimeUnit.SECONDS; private int getExecutionResult(WebElement element) { if (waitModel().withTimeout(timeout, unit).until(element(element).isPresent())) { return Integer.valueOf(element.getText()); } throw new QUnitExecutionException(MessageFormat.format( "Unable to execute QUnit tests at {0} within {1}{2}, timeouted.", pageUrl, timeout, unit)); } {code} {code} [WARNING] /home/kpiwko/devel/wfk/wfk-qa/build/drone-qunit-integration/src/main/java/org/jboss/arquillian/drone/qunit/QUnitPage.java:[80,65] [unchecked] unchecked call to <V>until(Function<? super T,V>) as a member of the raw type FluentWait [INFO] 1 warning [INFO] ------------------------------------------------------------- [INFO] ------------------------------------------------------------- [ERROR] COMPILATION ERROR : [INFO] ------------------------------------------------------------- [ERROR] V extends Object declared in method <V>until(Function<? super T,V>) T extends Object declared in class FluentWait /home/kpiwko/devel/wfk/wfk-qa/build/drone-qunit-integration/src/main/java/org/jboss/arquillian/drone/qunit/QUnitPage.java:[80,65] error: incompatible types {code} Further investigation shows that: until() methods comes from Graphene withTimeout() comes from WebDriver withMessage() comes form WebDriver until(String) comes from Graphene and seems to be leftover from Graphene1 migration. The problematic part is about setting FLUENT generics to null as this cause ambiguity on JDK7. I'd prefer to decouple direct WebDriverWait of Graphene from WebDriverWait of WebDriver and rather use a delegate. That way we can create until(long,TimeUnit) or even withMessage(String), withTimeout(long,TimeUnit) methods which will be able to interfere types even on jdk7. Marking this issues a critical. There is no workaround how to set dynamically set wait while using Graphene on JDK7.
