It looks like you were doing a build with make -jx where x was not 1
(probably 3).  Compiling HTML_401F takes a very large amount of memory
(and time).  I wonder if the out-of-memory-killer killed it.  That would
be consistent with the displayed symptoms.  jc1 gets killed by the OOM
killer and prints no diagnostics, then the gcj driver program reports
the error you see.

How much memory is on the system?  How much swap?  All of the objects it
looks like it was simultaneously compiling (HTML_401F,  javax/swing, and
javax/swing/plaf/basic) cause the compiler to use a lot of memory.
HTML_401F uses close to 500MB and can take 20-30 minutes to compile.
