@iOSXCUITFindBy(iOSClassChain) is not working

For me,

The following is not working:
@iOSXCUITFindBy(iOSClassChain = “**/XCUIElementTypeOther[label BEGINSWITH 'ALL'][-1]”)
private WebElement ALL_tab;
.
.
.
ALL_tab.click();

whereas, this is working:
iDriver.findElement(MobileBy.iOSClassChain("**/XCUIElementTypeOther[label BEGINSWITH 'ALL'][-1]")).click();

Appium version - 1.11.1
Java Client - 7.0.0

Kindly help.
