It looks like you’re hitting hotspot compiler bug.

If for some reason an upgrade to the most recent JVM version is not an option for you, as a workaround try to create a .hotspot_compiler file that excludes the call for org.zefer.html.doc.o.o00000

for example:

[language=java:fc72q1tt]#.hotspot_compiler file
exclude org/zefer/html/doc/o o00000[/language:fc72q1tt]
(the library is obfuscated, so the method signatures look strange)

BTW: could you please pubblish “VM Arguments” section contents of the crash report? Didi you overrire the default max heap size value with -Xmx parameter?
