The attached testcase requires gcc and gfortran, as well as a JDK

Oracle JDK 1.7, a single call to JNI_CreateJavaVM() changes the
behaviour of subsequent READ statements in the Fortran code,
depending on the value of the LC_ALL environment variable.
Can you reproduce this with OpenJDK 7?
Oops, I probably used the wrong name... I tested with the JDK that
comes by default with OpenSUSE 12.3, which should actually be
OpenJDK 7.
What happens is that the JVM initialization in JNI_CreateJavaVM() calls
setlocate. This seems to change the behavior of READ. I don't know
enough about gfortran to judge whether READ should follow the libc
locale or not.
