I found following files in my class-path
1.
schemaorg_apache_xmlbeans/system/sD023D6490046BA0250A839A9AD24C443/TypeSystemHolder.class
2.
schemaorg_apache_xmlbeans/system/s8C3F193EE11A2F798ACF65489B9E6078/TypeSystemHolder.class
but both are different files. Is this an issue ?
I put my tika app jar in separate folder under in .war archive and using JCL(my
war archive uses pdfbox jar with different version.So I put tika in different
folder to avoid jar clash) to load apache tika for attachment extraction. Is
this separate JCL makes any issue ?
