我的 java

版本是:

Java Plug-in 10.3.1.255 Using JRE version 1.7.0_03-b05 Java HotSpot(TM) Client VM

所以,当我有版本6.x一切都很好,升级后我得到了这个:

我将validateTree()更改为validate()和suprise;) – everthing工作正常,但我不知道这个更改是否也适用于 java 6.x(我猜不是).如何更改此代码以在Java 6x和7x中工作.

“这不是bug,它是java 7的一个特性”;)

This function should be called while holding treeLock

这是强迫你写作:

synchronized(getTreeLock()) {
     validateTree();
}
