osx - java os-x watchservice deadlocks -

-

i'm wondering if others have seen java 8 watch service on os x hang (deadlock).

i'm using watch service (obtained using filesystems.getdefault().newwatchservice()) monitoring create/delete/modify events associated files/sub-directories under directory. service appears work fine on windows, on os x appears hang when several new directories created in short time span. haven't had time precisely characterize conditions cause this, rapid directory creation , renaming of directories under folder being watched reproduces problem.

to precise, thread in our code invokes path.register() function (for registering directory watch service) appears hang following stack trace:

at sun.nio.fs.pollingwatchservice$pollingwatchkey.disable(pollingwatchservice.java:296) @ sun.nio.fs.pollingwatchservice.doprivilegedregister(pollingwatchservice.java:169) @ sun.nio.fs.pollingwatchservice.access$000(pollingwatchservice.java:45) @ sun.nio.fs.pollingwatchservice$2.run(pollingwatchservice.java:128) @ sun.nio.fs.pollingwatchservice$2.run(pollingwatchservice.java:125) @ java.security.accesscontroller.doprivileged(native method) @ sun.nio.fs.pollingwatchservice.register(pollingwatchservice.java:124) @ sun.nio.fs.unixpath.register(unixpath.java:897) @ myclass.functionfoo (myclass:xyz)    <----- invoke register() here.

looks bug# jdk-8079620 logged few months ago on openjdk site has similar set of symptoms.

any 1 else encountered problem? suggested workarounds?

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
