java - .Jar File Has Compile Errors When Decompiled But Works Properly -

i downloaded executable .jar file , used java decompiler extract sources. imported them eclipse shows me few compile errors such wrong types or calls invisible methods. hence can't run project without fixing everything.

how possible .jar file function though decompiler shows there logical errors? have compiler level beingness older (i utilize 1.8 while has been compiled using 1.6 or 1.7)? isn't compatibility kept though? did decompiler create mistakes?

how possible .jar file function though decompiler shows there logical errors?

the compiled classes in .jar file composed of bytecode, not java source. there no single transform bytecode java code. bytecode may well-formed, different decompilers may produce different results, , results not valid.

did decompiler create mistakes?

probably. happens. having written java decompiler, can tell straightforward.
