Description
A JNI local is generally deleted when:
1) the JNI method returns
2) it's wrapped in PushLocalFrame/PopLocalFrame calls
3) DeleteLocalRef is called
The problem is that a JNI local can be created inside an endless message pump (then the 1st point doesn't work), or out of the push/pop block (2nd doesn't work). Then the only way to avoid its leaking is to delete it manually.
(For instance, seeJDK-8145984 where missed JNI locals caused memory leaks.)
There're two more JNI locals to delete:
- AWTWindow.m, sendEvent: platformWindow
- CGraphicsEnv.m, displaycb_handle: graphicsEnv
