[Python-modules-team] Bug#683048: python-jpype: JAVA_HOME has moved

[David Gilman]

Package: python-jpype
Version: 0.5.4.2-2
Severity: important
Tags: upstream

I'm on a freshly-installed wheezy release and jpype can't find the path to
java.  The error originates from jpype/_linux.py.  Here's a reproducible
traceback:

>>> import jpype
>>> jpype.getDefaultJVMPath()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/jpype/_core.py", line 96, in getDefaultJVMPath
    return _linux.getDefaultJVMPath()
  File "/usr/lib/python2.7/dist-packages/jpype/_linux.py", line 36, in getDefaultJVMPath
    jvm = _getJVMFromJavaHome()
  File "/usr/lib/python2.7/dist-packages/jpype/_linux.py", line 55, in _getJVMFromJavaHome
    if os.path.exists(java_home+"/bin/javac") :
TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'


Java (both Oracle and OpenJVM) is installed in /usr/lib/jvm/foobarbaz and the
code appears to be checking in /usr/lib/jvm.  

As a temporary workaround setting the JAVA_HOME enviroment variable
explicitly will help jpype find Java and everything works fine.
