PropertyPlaceholder Value not resolved with ExecutorBeanDefinitionParser ("Invalid pool-size value [${task.executors}]") [SPR-6368]

[spring-projects-issues]

Willi Wurzer opened SPR-6368 and commented

I have

<task:annotation-driven executor="myExecutor" scheduler="myScheduler" />
<task:executor id="myExecutor" pool-size="${task.executors}" />
<task:scheduler id="myScheduler" pool-size="${task.schedulers}" />

${task.schedulers} gets resolved, ${task.executors} not

SchedulerBeanDefinitionParser uses
builder.addPropertyValue("poolSize", poolSize)

ExecutorBeanDefinitionParser parses the unresolved attribute
String poolSize = element.getAttribute("pool-size");

Added TaskExecutorFactoryBean so that all pool-size range determination happens in the FactoryBean stage (after any property-placeholder resolution).
