# The gamma launcher runs the JDK from $JAVA_HOME, overriding the JVM with a

# freshly built JVM at ./libjvm.{so|dylib}. This is accomplished by setting

# the library searchpath using ({DY}LD_LIBRARY_PATH) to find the local JVM

# first. Gamma dlopen()s libjava from $JAVA_HOME/jre/lib{/$arch}, which is

# statically linked with CoreFoundation framework libs. Unfortunately, gamma's

# unique searchpath results in some unresolved symbols in the framework

# libraries, because JDK libraries are inadvertently discovered first on the

# searchpath, e.g. libjpeg. On Mac OS X, filenames are case *insensitive*.

# So, the actual filename collision is libjpeg.dylib and libJPEG.dylib.

# To resolve this, gamma needs to also statically link with the CoreFoundation

# framework libraries.
