+Subject: Bug 569853 - jstack crashes Eclipse when running on Java 11
+
+1) Always call DetachCurrentThread if AttachCurrentThreadAsDaemon was
+called before, see
+https://docs.oracle.com/javase/8/docs/technotes/guides/jni/spec/invocation.html#detaching_from_the_vm.
+
+2) Specify JNI 1.4 version in JNI_OnLoad, see
+https://docs.oracle.com/en/java/javase/11/docs/specs/jni/invocation.html#jni_onload
+
+3) Added printf around attach/detach for easier debugging.
+
+4) Fixed build.sh to allow c99 standard for the for loop defined in
+DEBUG_CALL_PRINTS and resolve compilation error below if
+DEBUG_CALL_PRINTS is enabled:
+
+callback.c:1252:3: error: 'for' loop initial declarations are only
+allowed in C99 mode
+
+Main change is 1), it is a workaround for jstack / JVM bug described in
+https://bugzilla.redhat.com/show_bug.cgi?id=1897150

+Subject: Bug 569853 - reverted build file change causing crash on native
+ dialog
+
+Change on the build script was required to compile callback.c with
+#define DEBUG_CALL_PRINTS for debug output.
+
+Turned out, this change compiles something that GTK code can't
+understand & so it crashes with SIGSEGV on opening native file dialog.
