Hi,
I have
- subclipse 0.9.37
- Sun jdk1.5.0_06
- subversion-javahl-1.3.0-4.2 from Fedora Core rawhide.
I'm appending a crash backtrace. Summary is that javahl crashes in
native code after JhlClientAdapter.isAvailable() calls new SVNClient().
I debugged it a bit and it looks like a Subclipse issue, though it seems
like a lot of people would be seeing this so I might be missing
something.
I rebuilt the javahl native libs with some logging/assertions, and I
believe the problem is that the global initialization function for
javahl has not been called when the SVNClient is constructed in
isAvailable(). If you look at
org/tigris/subversion/javahl/NativeResources.java in javahl, when the
native lib is loaded javahl calls SVNClient.initNative(). subclipse
isAvailable() does native lib loading while skipping this step.
initNative() eventually calls JNIUtil::JNIGlobalInit() in javahl, which
in turn initializes the thread-local storage with
JNIThreadData::initThreadData(), which calls
apr_threadkey_private_create().
If initNative() is skipped as it is in JhlClientAdapter.isAvailable(),
then you would expect a crash like this one in
apr_threadkey_private_get() since the thread private stuff isn't
created.
I won't speculate on the correct fix, but hopefully if my diagnosis is
right one of you guys can fix it trivially.
Thanks,
Havoc
