Subject: [PATCH] Do not share key mappings with JNI object
|
|
|
|
The key mapping information between the native key mappings and
|
|
the KeyCharacterMap object available in Java is currently shared,
|
|
which means that a read can be attempted while it's being modified.
|
|
|
|
Because the code changed between R and S, this CL fixes it just
|
|
for R; the patch for versions S+ is ag/23785419
|
|
|
|
Bug: 274058082

|
Test: Presubmit
