v0.22.1Compare Source
Note: This release fixes several issues found in 0.22.0 which unfortunately required a few breaking changes.
Instead of bumping to 0.23 though, the assumption is that no one will yet be depending on the recently-released
0.22.0 and so we can yank that and have this represent the first 0.22.x release.

Env::exception_catchprovides a convenient way of catching pending Java exceptions and mapping them toError::CaughtJavaException(#736)AttachGuard::detach_with_catchlets you explicitly detach/drop a guard (like::detach()) and catch any pending Java exception as aError::CaughtJavaException(#736).JClass::get_namelets you query the binary name for a class, such asjava.lang.String(#736)Changed
The following APIs have had to be made fallible again, in order to safely check for pending exceptions before calling
JNI functions that are not documented as being safe to call with a pending exception:
Env::get_java_vm(GetJavaVMis not exception safe)Env::version(GetVersionis not exception safe)Env::is_same_object(IsSameObjectis not exception safe)Weak::is_garbage_collected(based onEnv::is_same_object)Weak::is_same_object(deprecated) and (based onEnv::is_same_object)Weak::is_weak_ref_to_same_object (deprecated)(based onEnv::is_same_object)Note: These are a breaking change.
Fixed in #733
