Seg Fault when trying to check if thread is attached to JVM

[jimishjoban]

Hello,

I am trying to run this command inside python console:

import jpype
jpype.isThreadAttachedToJVM()
Segmentation fault

Python Crashes and here's the Report I can see on MacOS... (sorry for the long trail)

We saw this issue when using python-boilerpipe and this line seems to be the culprit. Any help would be greatly appreciated...

Hey,
Even im getting same problem when i do something like this

import jpype
jpype.isThreadAttachedToJVM()
[1] 12696 segmentation fault (core dumped) python

Python version 2.7.3 and OS ubuntu 12.04

Thanks

Hi,
The exception is raised because no JVM has been started yet.

The following snippet should work:

import jpype
# Start the JVM first
jpype.startJVM(jpype.getDefaultJVMPath())
jpype.isThreadAttachedToJVM()
# Clean up
jpype.shutdownJVM()

closing this as invalid. See discussion in misja/python-boilerpipe#17
