The backtrace is somewhat inaccurate.  However, it seems that some klass
objects are not being correctly initialized:

...
klass=0x77afa164
klass->next_or_version=0xc0061a81
klass=0x77afa1fc
klass->next_or_version=0xc0061a81
klass=0x77af8b50
klass->next_or_version=0x0

(gdb) p ((jclass) 0x77af8b50)->next_or_version
$9 = (jclass) 0x0
(gdb) p *((jclass) 0x77af8b50)                
$10 = {<> = {<No data fields>}, static class$ = {<> = {<No data fields>}, 
    static class$ = <same as static member of an already seen type>, 
    next_or_version = 0x40062a20, name = 0x7714d2cc, accflags = 49, 

(gdb) x/4x 0x77af8b50
0x77af8b50:     0x7714d084      0x00000000      0x00000000      0x77afa530

(gdb) x/4x 0x7714d190
