java.lang.ClassFormatError: Invalid method Code length 69936 in class
There is a hard limit in the JDK class-file format of 64K, and there are some known issues in Derby which can cause the generated code to exceed these limits.
Tremendous improvements have been made in this area over recent months; are you able to try your test with the latest trunk code or with the 10.2 release beta? We'd love to have more testing of the beta release! http://wiki.apache.org/db-derby/TenTwoRelease thanks, bryan
