55 # The gamma launcher runs the JDK from $JAVA_HOME, overriding the JVM with a
56 # freshly built JVM at ./libjvm.{so|dylib}. This is accomplished by setting
57 # the library searchpath using ({DY}LD_LIBRARY_PATH) to find the local JVM
58 # first. Gamma dlopen()s libjava from $JAVA_HOME/jre/lib{/$arch}, which is
59 # statically linked with CoreFoundation framework libs. Unfortunately, gamma's
60 # unique searchpath results in some unresolved symbols in the framework
61 # libraries, because JDK libraries are inadvertently discovered first on the
62 # searchpath, e.g. libjpeg. On Mac OS X, filenames are case *insensitive*.
63 # So, the actual filename collision is libjpeg.dylib and libJPEG.dylib.
64 # To resolve this, gamma needs to also statically link with the CoreFoundation
65 # framework libraries.
