I am decompiling java application, and i have already done with 99% .class files. But, I have a problem with couple of them: error while decompilation (errors are same type). Example:
Procyon: java.lang.IllegalArgumentException: Argument 'index' must be in the range [0, 63], but value was: 15873...
CFR:
Can not load the class specified:
org.benf.cfr.reader.util.CannotLoadClassException: Modules_4.class - java.lang.IndexOutOfBoundsException: Constant pool has 62 entries - attempted to access entry #30318
JDCore: returns null
Jadx:

What is wrong?
There is nothing wrong with all decompilers i have mentioned before.
It was a constant_pool_count issue. It happened because of some JPHP decompiler offset troubles. So, if you are trying to reverse jphp applications, use your own software to delim .phb to .class blocks with couple of bytes before each of them
