spring - Hibernate 4.3.11 with c3p0 0.9.5.2 setCharacterStream causes AbstractMethodError -

i know issue has been treated in various question , in opinion answer in here seems logical solution, me somehow doesn't help. error occurs when saving or updating entity. others works strangely \oo/

here's stacktrace:

i clueless root cause now... related jpa config in languagetext entity class ? nothing fancy in there though...

thanks hints on this.

so found out issue was, , usual sitting between chair , screen. setcharacterstream method issue resolved adding real jdbc4 driver. chosed 1 microsoft itself. won't mention ton of issues came choice, solved problem stated in title.

for care: problem conversion stupid. had closer entity class , found @lob annotation on string field. well...removing it, solved issue of conversion. have no clue why worked jtds (i assume jtds more clever ms driver , has internal auto conversion such cases...) .
