Description Hiroyuki Inaba 2003-02-11 18:56:53 EST

I using Eclipse 2.0.1. 
The phenomenon that IDE does hang-up is occurred.
I want you to help. 

When the cpu clock is low, hang-up is sometimes occurred.
I sent the stack trace when hang-up is done.
I think that depends on the timing about hang-up.
I think that the problem is the locked time with synchronized is long. 
When the locked time with synchronized is shortened, hang-up has not been 
occurred. 

It is thought that the update method is good to shorten the synchrnized.
I want to get the advice from you. 

Example: org.eclipse.jdt.internal.core.JavaElement.java

[ Befre update ]

public JavaElementInfo getElementInfo() throws JavaModelException {
	JavaModelManager manager;
	synchronized(manager = JavaModelManager.getJavaModelManager()){
		Object info = manager.getInfo(this);
		if (info == null) {
			openHierarchy();
			info= manager.getInfo(this);
			if (info == null) {
				throw newNotPresentException();
			}
		}
		return (JavaElementInfo)info;
	}
}

[ After update ]  Note: "+++" is updated line.

public JavaElementInfo getElementInfo() throws JavaModelException {
	JavaModelManager manager = JavaModelManager.getJavaModelManager();
+++	synchronized(manager ){
+++		Object info = manager.getInfo(this);
+++	}
	if (info == null) {
		openHierarchy();
+++		synchronized(manager ){
+++			info= manager.getInfo(this);
+++		}
		if (info == null) {
			throw newNotPresentException();
		}
	}
	return (JavaElementInfo)info;
}

I found the long-synchrnized is 2 place in JavaElement.java, and 1 place in 
JavaProject.java.
